I do nothing with your information..but i enjoy watching very much..

I just tripped across this. Will try out the app as that interest me the most. I can make any electronics so that per for me is easy. If you don't want to take up your timers, you can always use an external clock and gate precise times levering the IRQ functions. That works great. Thanks for your work here. Really appreciate it.

Your videos just turned my lazy sundays into productive sundays!

Didn't even know about the ESP32. Gotta order some, thanks for the guide! :)

I think where I went wrong when I was trying to install the ESP32 Aduino setup was to use my current Arduino setup and just change it to do the ESP not thinking it would really screw up my other boards, which it did to no end When I finished, nothing worked and I had to rip it all out by the roots and start all over, giving up on the 32 and just being happy to be able to program my old arduino hardware once again. Next time I shall simply install it in a different location on my hard drive and I think that should work! Thanks for your great videos, I always learn something from them, and as I have always maintained, learning at least one new thing every day keeps our minds young, just as a walk in the desert every morning keeps my heart beating and my lungs pumping air as well. Ah the things we do for life....

Was building this with an raspberry pi zero, which makes programming it way harder. This ESP32 is exactly what I need!

Okay got it all sorted out in a couple of hours! Great Scott!! What a genius!

Thank you so much for this video, I can't follow many of your videos, but I love IoT and I have succesfully changed your videos idea to my project (controlling various relayswitches via an 433MHz transmitter and an NodeMCU)!

Well done. A lot to unpack but a really good starting point. One caveat: don’t use really strong magnets when testing the Hall sensor, as it will kill the sensor (yup, I did)

This video is great and super helpful just like all your others! Thanks man. 🤙

Oh wow, shades of the Lost In Space Computer!! I love it, one of my favorite series when I was a boy growing up in South Dakota! Wonderful information on how to get the little ESP32 running as well. I have several of them at home in South Dakota, when we return from our winter quarters that consist of our 35 foot Class A motor Home. (There may be one in my junk bag, I will have to check now I am excited!)

Love the ESP chips! Used it for my senior project! Cool video.

Just tried it.. In 35 minutes, I set this up and instead of sending voltage to a pin, I printed it out on the built in screen of the TTGO esp 32. Thanks a lot !

I have done this to make internet connected 443MHz relays and homemade sensors. Works pretty well and runs stable for long time!

impulse bought one of these from banggood and i'm glad i won't regret it now

Your videos really help me out with my own projects. I didn't know anything about the ESP32, but now I can modify some of my past projects. Thank you!

Thanks! I was looking for a guide to work with my project, and your video helped a lot

Very nice! Thanks for sharing this :) My current project will get similar functionality using a M0 bluefruit board. The ESP32 got me thinking though for future projects. Haven't heard about the MIT app inventor project, will definitely be checking that out!

Scott, you really are the Great Scott! Thanks.

was literaly just looking for a video like this, thanks man love ur vids

thank for your videos , people like you are the salt off this earth !

I've been struggling with the ESP32 and LED driver libs. Good to know it wasn't just me :)

Amazing Project, about your error message with the app, use a POST method instead of the GET method and that should remove the error. A Get method expects a result from the Server and a POST method sends data to the server. Keep up the amazing work, you really are amazing at the electronics

Brilliant, you made me think that "why not just build an iot project with the esp"... I think I will start soon

ESP32 rocks! Great video Pascal

i love all the videos and find it to be allot of help with my electronics basics..request- robotic arm or LIDAR sensor

thank you very much

Very nice job. You don't give up easily.......thanks

nice work thinking about the vast implementation it can have :D

Cool Video as always. It really helped me out. I created an App to control a motor that opens my curtains, using the ESP32. I couldn't have done it without your help!!!. (Well maybe I could, but it would have taken A LOT longer). Thank You!!!

GreatScott is always the best!!!!

If you had the server return a 200 status code in a response, you could avoid that error code in the client. Great video!

Dear GreatScott, Thanks a lot for your nice video. I'm teaching code and IoT to kids and I use ScratchX, AppInventor and ESP8266 and I've developed many projects with them. And you inspired me a lot of ideas to share with the kids. For the error notification you got on the app, just add an empty C-Shaped block from Screen object "When Screen error Occurred" : all notifications will disappear

Nice project, love the design

wow! that ESP32 Board sounds awesome :D

As always, excellent work and video

I'm working on a vastly different project but this saved my ass. Thank's! (Especially for the Android App creator tipp!)

Excellent video, informative and easy to follow. Thank you. Subscriberd.

Thanks for the review... i will buy it and see what i can do !!stay creative

Really, really nice, man. :) Tons of good projects out there to that board. :)

Great Start! Thank you for useful content Maybe try to implant Color Chord2 onto the ESP32 for better performance? It will look gorgious.

Was just looking into this. Thanks!

After watching this recently im not sure if you had your color order set wrong WS2812B is GRB AFAIK and also Fast Led has its own delay function I believe :) so if you havent checked it out recently it might be worth a try ! I use a NodeMCU with my WS2812B 240 pixel strip and it was the perfect addition !

Thank you GreatScott!

thanks man. i was having anxiety because I promised this functionality to a client without even doing research... looks like I didn't need to after all ( except for your video, thanks n_n )

Those videos are getting looonger 👌 love it 💜

Can you do more of these? I like seeing how to develop apps that can control projects like this

I like the APA102 library, which uses its own protocol running over SPI. It's pretty easy to implement a low level control yourself using that. Also works better with hardware or operating systems that aren't fully real-time.

Love it! Can't wait for more Pi stuff :)

Kool project! thank you very much for being an inspiration to others like me :)

Good video. This is the way to study esp32 uC

I've been tryiong to figure out what the WiFi module does. Now I know that at least it can talk HTTP, which is a big help.

You only need timer interrupts when you need very very precise timing... In this case you can just use millis or micros to check how much time has passed and only execute certain code in specific intervals, since it doesn't really matter if it executes a few milliseconds later.

Nice work man! It's amazing what you can do with Arduino.

Hello! First, great video as always! To all who also try to work with the ESP32 and fail, when I tried with my chip the simpleWifiServer example, that did not work and the chip has constantly disconnected from my PC and reconnected when Wifibegin was running. This is because my PC has turned off the USB port because too high current flows. So if you have the same problem then connect an external power supply to the ESP32 and the problem is solved! LG EK

Very good skills GS. Very nice work

Best video so far!!! GJ!

Thank, very usefull for my project. Can you create tutorial or some project using raspberry Pi 3 ?

Brilliant tutorial. Really inspires me to do more with electronics!

Hi!! I like your all projects..

Taking this, adding some speakers at the corners and making the pattern sync with the music. Would be so cool :D

Another GREAT video, thanks.

Wow u have a great knowledge of electronic

ESP 8266 are still very great chips, even if you don’t care about using it for anything in particular they are great fun to mess around with and host servers. Plus they are pretty cheap (node mcus esp8266s are around 13 dollars for 3 chips)

I have enhanced my electric window blends to be remote controllable by esp8266 relais modules. I had to implement a way to send a few simple commands like up / down / stop / reboot and identify also. A HTTP Server is a lot of overkill to achieve this. Instead I send simple single character TCP-Messages to the esp8266, like "u", "d", "s" and so on. I also wrote an Android App to control the blends and a Java command line program that simulates presence while I'm on vacation. The Android IDE is fairly easy to use. No barrier for an intelligent fiddler like you are ;-)

Great video man!

Great job on the video. I really liked it. Could you please do a video on ESP32 triac control? I think that would be very interesting. All I have found is high current mosfet pwm control for AC loads. What do you think? You seem to be very knowledgeable about the ESP32. Thanks

another great from great Scott.

I did a similar project to open a garage door with my phone. But I used a app called http request widget. Works great and let's you put a widget right on the home screen.

Nice project! I'm working on a bluetooth controlled rc car! Hopefully it will work!

Great Video. By the way you solved my problem with android http request. Thanks.

I built a 16x16 RGB board and have been using a RPI to power it. I think it's a nice solution because I can run code that pulls from weather underground and display it along with other fun animations. Definitely not the cheapest solution though.

This is why people love you

Thanks dude I just wanting this

Wah! Finaly somone with know difference between units :)

Really great scott!!!!

I love your projekt :-* thx

i love your vids man your soo cool

Great project!!! I was wondering if you're planning to make a project that sends analog signals to the esp32 using the arduino ide and maybe processing?

Awsome video, but I forgot why I wanted an arduino with wifi build in. :D

You should make a tutorial about a 555 timer flyback converter or about wifi or bluetooth jammer.

One possible fix for the android could be to let the esp send a 204 status on every URL you specified with a function this should get rid of the error because 204 stands for "no content". sending 404 on every URL would also work but will probably end in another error saying that the server couldn't find the requested data. i don't know what client.flush() exactly does but i think giving a proper response header with 204 is a way more elegant way of doing things. still nice addition to an already nice project ;D

Love ur vids

Bro . As usual great video. Who is here dor 30 views. First time:))

this is amazing, i think im going to build one of those some day (Y) I have an idea for you, have you ever thought to make a custom game controllerbased on the arduino pro micro? Would love to see you make one :)

WOW loved it!

Thanks,this great scott...

Fascinating.

GREAT VIDEO sir.... I was thinking is it possible to use Nextion display to enter WiFi credentials without hard coding or without creating a Soft AP

Very usefull and nice video, thx I will buy a board

Great video.

Excellent video 👍🏻👍🏻

you rock man i was rellay helpful

Interesting project

Hello, there is a newer version of MIT app inventor called Thinkable. It's still free and from MIT, but with a few more commands

Love your videos! I'm creating a 800 pixel matrix for a ceiling install. Is it possible to setup in a way where I can use designs I made with LED Edit but also have an audio reactive input with a microphone connected to the ESP32?

Nice video. Can you please make a video on how to show a sensor analog reading by using this nodemcu with an arduino board inside a websites or an app.

Friend, today at 8:30 pm, I'm going to post a short video about a project I set up for the new electronics magazine, the project was saved for a few years and was almost completely finished, I'm going to do a restoration soon, clean up and finish what I missed to finish it. In the video I will only present what was set up at the time, the way it was until today. Original Language Português Brazil

You are awesome always.....

I really would like to see you invest in a fine tip soldering iron and some lighter guage hookup cable. Would make your projects so much more tidy
