I can never understand how some people can put thumbs down on any of your videos.

Most comprehensive NRF robot car in UKposts by far! Thanks! It really helped a lot understanding NRF module. Take care man. 😊

You seriously have one of the best channels i’ve seen! Quality videos and quality information. Keep up the good work!

I can only echo what so many others have said, in one word, "Fabulous" ! The quality of your videos are amazing, information is precise, relevance is on the money and most important just plain fun. Thank You for spending the time to share your passion to educate the rest of us!!

Dronebot , your videos are setting fr the standard for learning. You are thoughtful, concise, detailed and thorough. I just wish there was a teacher like you in every field.... 👍

You are super awesome teacher...... You don't leave anything about the topic and explanation is excellent 👍

I mean you know you are a life saver and a great teacher. Thank you for the lecture! On a side note, I have the same digital clock you have on your work bench right there. Makes me hope I can get my workspace that clean and organized one day :)

WOW. One of the most comprehensive videos I have ever seen. Amazing video quality and editing too.

...our reward - watching the next video!!! Thank you for sharing...

I have been doing this project for almost 2 years,but never success,then my friend suggested me to your website and it looks great! Gotta try it soon.

Excellent job. Your work and presentation is exceptional and has me hooked to your channel. So far I've learned a lot from you. Please keep up the good work. Kind regards

you are an amazing mentor, tutor what do I say! I learnt so many things from you that I didn't even learn from my course teachers!

Really good explanation. I failed miserably in the past trying to achieve this very setup 😆 on an Atmega 32 in C++, switched to Arduino a while back but never got around to try again. Thank you so much for going into sufficient detail, but not too much and taking the time to creating this content! Off to try again! 🏃‍♂️

Indeed a lot of detail, perfect! Many details i already know and understand. Some details though are crucial for me to properly understand the stuff I need to understand. The detailed explanation is a good thing in this case. Thank you for te great video!

For anyone in 2023 trying to make a wireless car with the steering controlled by a servo, it will work, but you will need to download the ServoTimer2 library. Also the number to insert in the servo.write() command will need to be from 1000-2000 or it will not work. For the normal servo library, its from 0 to 255, but for the ServoTimer2 library, its 0 to about 2300. Also, if you want to prevent the motor from spiraling out of control, make the max analog output to the motor driver be around 20% less than the actual max, so instead of writing from 0-255, make the range 0-200. I did this and it tremendously increased the stability. When I had it from 0-255 and I went full speed for a few moments, the motor would get stuck on the max speed, but when I made the max analog out be 200, it never got stuck. These are some of the problems I ran into after working nonstop for 10 hours, but I eventually got the entire thing to work!

This proved to be very useful. Thanks Bill!

Another interesting video. I need to pickup some RF modules to experiment as Arduino and Radio Communication is something I'd like to investigate. Thanks again!

Excellent teaching! Your voice is easy to listen to and I appreciate that you sound like someone I would know. Accents are sometimes hard to understand and since we come from the same part of the world, our dialects and accents are the same. Therefore I don’t have to work past that first to get to the great content you have. Straight, to the point, and well written beforehand and not just made up on the fly with tons of stutters repeats. Thanks again. Now my number one source for Arduino tutorials.

Thanks a lot. I am from India and I ve successfully completed the project you are telling about. You did help me a lot to understand and completing the project with in first try. Your long and more informative videos are great for beginners like me.

Great job as usual. Really enjoy your shows!

Really enjoy your videos, had to pause the video just to let you know! :) please whatever you do, don't stop making them! :)

Thank you for the excellent video - very professional. You provided a very thorough and detailed method to follow. I can't wait to get started on my own project.

Thanks for all your hard work doing these videos.

When he mentions reversing the pins on input output, that means swap the MOSI pin with the MISO pin on the adapter. (pins 11 & 12 on the arduino.) Thanks Drone Bot!!!

This was awesome. i made my own using arduino nano and a shield. Thanks Bill.

Who the heck are you? I don't know of anyone who can explain things so fast. so complete, and tolerable. be it voice, tone or speed of speaking.. Wow, I found a gold mine here. Thank you Sir. On my journey to save the world from corruption, evil, and deceiving government, religious, or what ever people are doing to destroy our beautiful world. Know there are people out there doing really big things to fix things, and you are a big help to ID10T's like me. One thing you could do for me if you would? If you could configure the eight array antennas' for the Van de Graaff generator's, for E=mc^2. Thanks, you the man!

great video, I don't really understand why few minority would dislike the demo, it must be that they are dump or something. Keep up the great work :) thanks a ton

Great video. Having the same issues as others...too much latency in rcvr response. Reduced delay value to 10ms, but still having issue. Also would be nice to turn both wheels when direction change is activated.

Your videos are super! I cannot thank you enough!

You are a super kind teacher. Thx!

what can I say, Thank you very much. You become my mentor, and I am proud

Many thanks, I´m always referring to your videos as its clear instruction for Arduino. I built a few of these over the holiday including my own spin on the HW using a really nice Arduino Nano and shield. I hope its ok I put a reference to you in my Thingiverse build as my bias is more HW. I managed to squeeze in all your sensors on a easy to print version. Dave

Thanks for your Chanel and your hard work, I studied electronics for many years, in different country, they thought so many things except how to program or build robots from scratch. Electronics terms and procedures can be very confusing and challenging, thanks for simplifying them.

Haha, glad I watched until the very end to see the bloopers!

thank you for the video! the Radiohead library with the reliable datagram code is the only one that's working for the NRF24L01 modules I got. I also like your code because it's simple and efficient. Yes, it's better to figure out the joystick position at the transmitter and then send just one enable command vs sending the joystick encoded value to the receiver. I will use this code to complete my RC tank project. :)

Sir, your workshop is very well organized. I like so much

From tunisia 🇹🇳 i want to thank you for all your efforts and the excellent explication for everything ... thanks a lot again and bravo continue ❤

Thank you so much for all the great videos and the teaching you do on UKposts for us Respect!👍

Great tutorials, Sir! @33:00 you picked up a wicked echo. :-) I am sure you know. Remember "Test for Echo"? Not my favorite Rush album but I love Rush as I am sure you do, also. 2112 and Permanent Waves and Signals. Pretty much everything up to Signals are my favorites. RIP Neil.

Another great video Bill. Hope you are keeping well.

Teacher, excellent video and explanation, I'am learning a lot. thank You

With respect to previous comments, I think the videos are of a perfect duration, in that all important aspects of a project are covered completely. Too many "explanatory" vids go to "I'll cover that in another video..." Sometimes I'd understand if their presentations were as rich and explanatory as Mr. Bill's, but more frequently it's someone just drawing stuff on a piece of paper. I don't know if the graphical and animation aspects are contacted out ... but their like watching Fantasia in a world of Beavis and Butthead animations. Now with two vids a week, no one can complain.

that was thorough, very calm and very clear. thanks sir

Thank you so much! This video saved my lunar rover project.

Awesome awesome teaching sir. TY so much.. have you ever done one of these videos with and rc receiver and controller. I have built this one following your teachings but could you add an RC receiver instead

Sir , I am so amazed with all the videos and projects that you have done ! They inspired me to think and try about different other aspects of these projects as well. But I am stuck at one doubt . How do I make this very wireless robot car GPS guided ?

I ve made it two times, but it works like a charm

Great video, I would like to ask is the maximum distance I can control, thank.

Thankyou So Much for the Video Explanations.... Very Easy in Understanding..Intresting too. !!!

Thank you so much for this tutorial it was immensely helpful! I have faced one problem however... Everything works well, but on my client side I notice that my car's NRF module stops receiving the coordinates from the joystick. The serial monitor shows a few lines of coordinates and then it just stops. Sometimes it picks up one or two more lines sporadically. When I reset the joystick it receives a few more lines and stops again. Any idea what the issue is? I would be thrilled if I could get this to work well. Thanks a lot for your time and effort! It's appreciated

excellent video. A long one, indeed, with a lot of information to process. It'll keep me busy for a few days!

Superb Video... i Have learned so many things its great.. i will be highly grateful if u will upload any tutorial on 2-way communication using these NRF24L01 modules..

Thank you very much, sir, for the great videos you are a great teacher How many meters will the signal go without an external antenna

Great video! Thank you so much for these detailed videos and instructions. Would love to see one of these builds with the esp32 and motors with built in encoders. Those are fairly cheap these days. please Please PLEASE! Would you? ... please.

Congratulations on the tutorial, I would like to make a rover, with ps3 control, usb shield and nrf24. But I'm not able to run the usb shield with nrf24. I am using two Arduino UNO (TX and RX). Thank you for your help

Dear Bill: Thank you SO MUCH for all of the help and inspiration you provide to we Aduinovians; I've learned more than words can describe. I thought I might share something I've learned along the way that may help others on a project like this. If an individual is running the Arduino IDE using Windows 10, there's no need to have two computers to observe the communication between two NRF25 WI-FI breakout boards. As long as there are two COM port plugs on the computer, and there are two USB cables to use, here's the trick... First, connect all of the wires between the two wi-fi breakout boards and the two Arduino boards, and open the Arduino IDE to get ready for testing. Open either the client-side or server-side .ino file of the NRF24 project being tested, and plug-in ONLY ONE of the Arduino boards using a USB connector cable to the computer's first COM port. Compile and link the .ino file and upload it into one of the Arduino boards. Make note of the COM port the computer assigns to the connection. Next, right click the Arduino IDE's tab at the bottom of the screen (or wherever the open-program tabs may sit on the screen), and OPEN ANOTHER INSTANCE of the Arduino IDE (don't open the second client/server-side .ino file being tested using the same Arduino IDE as the first). Now that there are two separate instances of the Arduino IDE running, connect the second Arduino board to the computer's second USB port using a second USB cable. Compile, link, and upload the second .ino file being tested into the second Arduino board. The two different instances of the Arduino IDE are now running two separate .ino files on two different COM ports, and two seperate serial monitors can be opened to watch the communications between the two separate WI-FI boards. NOTE: The IDE has trouble when two copies of the SAME .ino file are open. The second instance of the Arduino IDE will most likely open with a copy of the SAME .ino file that is open in the first instance of the IDE. Be certain to close the initially open (copy) .ino file from the SECOND IDE after the second NRF24 file has been opened in the second IDE. If you close the first copy of the two .ino files open (of the same name), you just closed the first instance of the IDE, and now, one IDE shares both open files again (sounds more confusing than it really is). If something goes wrong, say my two favorite words, "oh well," and try again. It's important to follow these steps in order and to remember which Arduino board is connected to which instance of the Arduino IDE, which .ino file sits in which Arduino board, and which COM port each the the Arduino's communicate through. When coding modifications are involved, it's easy to forget which board is the server and which is the client (or, am I just getting too old?). Thank you, again, for your time and effort in sharing your wealth of knowledge. I'll be joining the DroneBot Workshop Forum just as soon as I get my MS email account password sorted out (that's it...I'm too old). I've only known about Arduino since early January of 2020, but have a I have decades of experience in DCv SCR-drive electric vehicles, and I was coding Turbo C in the early 1990, so I have a lot of coding experience to share. I look forward to the experience of the Forum. We have a lot to talk about, and I love to gab. Stay well and take care; Casey aka itsCaseyDambit

wow..great video ! thanks again !

Thank you so much. I'm relatively new to all things Arduino, IoT etc. I have never coded before and at 67 yrs just loving every small success. It'll be a while before I can get everything together for this one. You explain everything so clearly & certainly "know your stuff" & 100% agree with "TheMarbo74". I fully recommend your videos to anyone interested in electronics. Keep doing what you are doing.

Great video and explanation!

Thanks for your tutorial sir, but my setup takes too much response time how to rectify that? Also I am using 9v battery for powering both Arduino and motor driver instead of 12v, whether this may the reason for delayed response?

Thanks for your all videos

Hi there! i realy enjoy your lessons. and i was wondering if its possible by using arduino uno (or micro) with wifi (wifi over things) meaning controling things by using arduino uno (micro) over internet

Thank you for your time

A truly awesome, very informative and flawless video. Surely will try one day.

At first I want to thank you for all your excellent videos! They might be a bit long but you go into detail and I love it. I started a project like this by my own but I want to add a few things. One of it would be to add an LCD Display to the joystick to show me the Information of the Sensors but I am not sure if it is possible with only one nrf24L01 or if I need 2 of them each ardiuno. It would really help me if you have an answer for this.

Cool video, do you know the practical range of those antenna'd modules. For example, what is the max range inside a home

excellent tutorial! thanks for the detained instructions and reasoning...

Thank you friends 😍

Thanks a lot for your excellent lessons! I am trying to use a Funduino joystick instead but unfortunately I can´t make the car stop or turn. Forward and reverse are working fine. Any chance you could explain how to make it work? Best regards.

Great programes & as a 78yrs old I am trying to find witch two wires you are suggesting That were swap around (Input & output) as I am new to wireless controls With the nRF24LO1?

Thank you SO much for this great instruction video. I never could have build this on my own from scratch. I really love it and will soon share it with one of my grandchildren. Hopefully he likes it too.😀👍👍

Hi, well made and explained video, I'm trying to hook up the same kind of car with my homemade Arduino transmitter and receiver. How would I make it so I can use 2 joysticks instead of 1, so I can control forwards/backwards with the left joystick and turning left/right with the right joystick, what would I have to change in the code if I were to make such change? Please reply as soon as you can, thanks in advance! Cheers, Max from the UKposts channel "Max Imagination"

A great project as usual.

Sir can you please work with the SIM800L GSM module? please? I have searched the entire internet but have not found a good and simple tutorial. You do an amazing job explaining everything in detail. Sir please make a SIM800L GSM module tutorial video. It will do wonders.

Thanks very much for your sharing. I tested my robot car as you taught, but the joystick side always shows "sendtoWait failed",could you please provide me some possible troubleshooting techniques? I would be very appreciated. Thank you very much !

One of the best video I see on the net with crystal clear explanation and code

Great video! Thank you! I have got question - I was testing two pcs of NRF24L01 (bought in Aliexpress) with adapter, but it appears that none of them was working. I was trying ling 4-5 times, counter-check everything several times, checked adapter - yes it gives out 3.2-3.3V, checked all pins. Sketch is as simple as possible, but nothing. You mentioned that is is possible that if NRF does not work then I have to change data pins - what pins exactly I have to change? And what do you think - could it be that both NRF modules I got are damaged? Thank you for helping me! Have a good day! Valters

How to change cn and ce pin in the setting. Pls I really need know. My pins are already occupied. I only have 10 and 2 and my board is already set.

Excellent explained!

Very helpful, interesting and informative video. I am going to play with some RF modules to make a low cost Robot Car to accomplish some household activities. Just one question here - what about 433 Mhz RF Transmitter and Receiver Module, any drawback or major theoretical difference? Will be very helpful f you reply or make a video of comparative analysis of different RF modules.

I am wondering if you can do a video with proximity sensors and beeper. I have a Harley trike that I am going to experiment with and can not tell how close I am to things when backing up or to the sides of the widest points at the rear. Thought this would be a neat project and very inexpensive. Thanks and keep up the great videos.

Thanks a lot for this well explained video and concept. Indeed u make technology look very easy and practical to grasp.. but I have a challenge yet unsolved, when experimenting with the reliableDataServer / Client alongside with sensor(joystick), the transmitter is cable of sending data(joystick values) but at the order end(Receiver) , it shows *init failed* on the serial monitor… I have tried troubleshooting to no avail. Pls I need help…Thanks

A great and outstanding project.Thaks

Your workshop is nice

Holy camera switching Batman!! 😂🤣 Great tutorial!!

This is a great video. I am trying this robot car. Though I encounter some problems on the transmitter side it says "init failed" on the receiver side it says "sendtoWait failed" and there are values given by x and y axis. Is there a problem using a clone arduino UNO as receiver and original arduino UNO as transmitter?

can you show us how to use these to control multiple servos, because i have looked up alot of tutorials on youtube and all of them dont explain it very well

Where could be that Labeling issue on that adapter board you mentioned ? My adapter board also having issues in configuring. Where could be that labelling to check for ?

Your job is outstanding. Excellent. Question.... can i use 12v or 24v motors, if yes, how?...

hello, once I stop a wheel to turn the car, the engines will reverse, so one going forward and another back, as if it were the movement of a tank, what would change in the programming?

thank you for the video!

great video, sir! can you please tell me how to add joystick and motor in the code? thank you for a ASAP reply, sir.

Well, I got my car working. I had to adjust the joystick values, mine went from 0 to 220. I used a car like yours but the kit came with 4 motors the right side two motors are wired in parallel so is the left side. It works ok but I can't figure out how when turning right or left how to get the motors to turn opposite of each other so it makes a sharper turn. Any help would be appreciated. Agan thanks for the VERY good tutorial.

Thanks for the information it was of great help

Thanks dude your video was amazing

gotta love the smooth side turn at 3:18 XD

great video. Thanks

What about the speed of bot? And also , what if we need to turn it on the spot i.e. one wheel going backwards and other forwards. Please, elaborate this.

Thank you very much sir!

I was wondering if you would have used spi for transmission? I'm trying to hunt down interconnect My nano and esp32cam. While I could connect to the cam separately, it seems a shame to waste a nano if you can also connect via the WiFi. I understand that a controller is still required, as I don't think the cam has many ports that are usable. (Was hoping it had two to be useful as a cam pan and tilt)
