This is extremely helpful and well done. Thank you for the work you've put into this.

great tutorial that goes in depth to explain; needs stuffs like that teaches under the hood mechanisms. Thank you for content

Great Video!!! i did the steps and it worked. Just FYI make sure you put resistors between the bluetooth rx to arduino tx. two different resistors of 2.2k and 6k would work. the reason is that you need to adjust the 5v to 3.3v.

absolutely perfect. Thanks so much!

Great tutorial, thank you!

First off this was a great video series and was glad to find videos that really go in-depth into explaining how to implement things like Bluetooth. I do want to know if this tutorial will work with any BLE Bluetooth modules(preferably HC-08) since I believe that iPhone only connects with BLE. I want to use the App inventor to create a remote for my projects in my Engineering class in school and only have a iPhone. Thank you.

Video provided great help for our project. Thanks

Very well explained video, thank you.

THANK YOU! Great video

Excellent Sir

I got the 1000th like. Very helpful video!

This was an amazing video explaining the bluetooth receiver! I want to make a project where on my iPhone I can send the device an "on" or "off" signal and for the arduino to read if it is on or off (0/1) and turn a servo motor. The goal is to remotely turn on or off the lights in my room. Do you have any suggestions as to what bluetooth receiver I should use to connect to my phone and how I should go about this?

Can you use a buck converter to reduce 5 volts coming from arduino down to the 3.3 instead of using resistance and dividing method you use?

You're a lifesaver

Nice vids, glad I found you. I'm a bit confused. My project needs multiple receivers. It seems that HC-05 can transmit & receive ? As they seem identically priced in most places to HC-06, is there actually any need for HC-06s ? Also can multiple receivers operate simultaneously? Or is it restricted with 1:1 pairing of some kind.

Thanks for the great video sir! Though I have a question about the code, for the pinMode(), why do you use rxPin instead of 9, as 9 was being set as a variable for rxPin on the top?

Thank you that was so helpful! Where did you write the code exactly?

Excelente.

Thx you

Voltage out for the resistor of 2.2 K and 5.7K is around 3.56 volts, i suggest replacing the 5.7K with 4.4k, since this value is hard to find, try 2 pcs of 2.2 K in series to get approx. 3.29 volts

This lesson is so so good! Thank you! I am watching this because I want to connect my wired mouse to arduino and arduino to macbook air via bluetooth (basically I want to make my gaming mouse wireless - with bluetooth). I want to create this because the usb hubs found online are either too expensive or so crappy (and damage my macbook air battery). So, this bluetooth-arduino based bridge would fix my issues. What do you think about this?

Very good

Trying to integrate my arduino and an application known as Processing 4 from my laptop to the board , any suggestion on which paticular one both sound tempting but cant decide.

Why are you not using the preferred resistor value?

Do you have any code with Arduino and HC-05 that can control a 12V fan, I really need it for my project, plz help me out

Hey @BytesNBits when I did what you did, the Bluetooth Terminal got connected but when I try to send a msg with a semicolon it is not printed in the serial monitor nor i am getting the return print in the terminal back again. I checked the code and the wiring everything seems to be perfect.Both the Baud Rates are also set at 9600. Is there anything else I can do to trouble shoot?

Hi, i would like to ask about the bluetooth module, once a mobile has been paired to a bluetooth module, is there any way for the user to retrieve the setup’s indoor location, is it even possible to track the setup of NodeMCU esp8266 by depending on the bluetooth module? since neo6m gps modules doesnt really work indoors

I recently purchased a hc 05. When I power the Bluetooth, sometimes it blinks and sometimes it doesn't. The same is with the connection. Also, when I transmit any data from the mobile application, the Bluetooth doesn't send it to Arduino. Should I ask for replacement

sir i do want to turn on and off led with pic16f877A and bluetooth HC06 module .but the blink is not stopping in the n=bluetooth module

Do you need to pair the module with your phone every time you use it or only the first time?

Do you know how to adjust this code so that it will work with an arduino nano on pins D4 and D5? I tried changing: const byte rxPin = 9; const byte txPin = 8; to const byte rxPin = 5; const byte txPin = 4; but the arduino nano is not receiving my commands from my HC-05

It's frustrating reading all of these successful efforts. It all looks so well explained, but, while my phone sees the HC-06 module, I can't get my phone to connect to the HC-06. I purchased two HC-06 modules. When trying to make a connection using 'serial bluetooth terminal', one of my modules consistently returns the message "Connection failed: write characteristic not writeable", the other one consistently returns a message "Connection failed: gatt status 133". Can anyone suggest solutions?

this works, except the receiving on the app for "laser off;" is "Ylaser on;", "Y laser on;", "Y;", and a few other mashups. Why does it do this?

Good day sir Is it possible to make bluetooth gps tracker with bluetooth module and neo 6m gps module? Thank you in advance

Do you have a project-like document write up for this ?

Please tell me... how are you achieving Arduino simulation? All I get is "NO SPICE INFORMATION".

Thank you for the video I just subscribed. I have a question when you first run it on Arduino and if i type on my phone's terminal "green;" I get a result: You typed green Now if type after another word or the same there is a gap after the "You typed" I get a result You typed green And that's a problem for me since i have added a red led and a green led . When the program runs for the first time it's ok , writing for example in the phone's terminal "red;" or "green;" it lights up the desired led but if I write again "red;" or "green;" the program doesn't recognize the word ( I suppose that's because for a reason i don't know if you type for a second time it's like the word has the enter in front it??maby?) . How can I resolve this issue?

Is it possible to use speech using this system on the phone to trigger the Bluetooth module

Good day Please I want to create a simulation for bluetooth controlled fan regulator using proteus I haven’t seen anything close to that online

sir, what is name of program you used to design curcuit in 5:45

Since I am using an iPhone, I am using other apps that say to support BLE to send the messages. However, it seems like the "pairing" never happens; it just connects straight to the module on the arduino (indicated by the LED stops blinking). Then, when I send any signal from the app, nothing on the arduino serial monitor ever shows up. Is this a common problem? Thanks in advance.

how do i connect it with a shield groove i looked everywhere but nobody is talking about it

Can you make a complete step by step video tutorial of how to send messages/texts to a display using an Arduino board (Nano/UNO), HC-05, MAX 7219 and MIT App creator? This would help me and a lot of people out here. Thanks.

what if you accidentally wired 5 volts to the ground of your hc05? will it short circuit?

hi,my hc-06 responding for AT commands, but when i got to this video i did everything just like you (copied the code) and my hc-06 is connecting with my phone via serial bluetooth terminal and it says connected but when i type message i dont get answer. Im strugling over a week now and i dont know what is wrong. First i had problem with even answering to AT commands but i manage and now it is not responding back for instance for "hello;" :(

Hello sir, i followed your video step by step but somehow i wasnt able to pair with the module as it simply didnt show up in the „avaliable devices“ section. Does this not work for slave modules? And if it doesnt, how would one talk to a slave module?

I am using HC 06 module but after connection with ardino uno led in Bluetooth module is not blinking. Please help to solve this problem.

what arethe value of the 2 resistor?

I am able to get the messages from terminal to my computer, but i can not send from my computer to terminal. I got it to work before, but when I tried redoing it, I can not get it to work. Please any tips????

can i send message from serial monitor to terminal

Why can't you just plug the TXD and the RXD into the TX and the RX on your arduino aka Digital pin 1 and 2?

I think the calculations of the resistors is off. I = V/Rt = 5/(2200+5700) = 0.0006329114 * 2200 = 1.39Vd when it should be close to 3.3 correct?

These libraries hide to much information. Is the bluetooth module in master of slave?

Could you make a pinball game ? I Love Pinball Games :)

I received an error while uploading the code to my arduino

Canyou send the code
