Hi Mehsah, I'm happy to know you found this MIT app inventor and Bluetooth HC-05 tutorial useful. Wish you all the best for your competition. And hope you'll great great bluetooth mobile app. Good luck and Best wishes!
Thanks to add so many details on this video, is not usual to have long videos in youtube but this one was very helpful to understand the whole picture.
Why do you need the Serial.print(Incoming_value) and " "? is it required by the blue tooth protocol to echo back what you received? I am curious because no class is listening, so they would just accumulate in the blue tooth buffer. Or are you using simultaneously the monitor through the USB interface?
Hi, great video but when I try to pair to the Bluetooth module to my android phone it just says pairing for a long time and then eventually stops trying to pair.
Hi Please check App settings where you've to allow permission. And then HC05 Bluetooth will work with Android App. This is because many mobile comes with high security which restrict Apps use. I hope this may help. Good luck and best wishes!
Take note that this would probably fry your HC-05 module eventually. HC-05 uses 3.3V logic while arduino is 5V. This means you are putting 5V on the HC-05 (3.3V) RX pin. There are a bunch of tutorials for HC05 that specify a voltage divider for the RX pin.
the bt module is 3.3v and arduino is 5v on rx and tx so how did you connect it without blowing it up. I've been told to use resistors to reduce voltage. can you confirm if this is necessary or not
Hi Rushaan, on hardware side we've used "Arduino IDE" and to make mobile app we've used "MIT App Inventor" which uses blockly from google. I hope this may answer your questions. Good luck!
seems like the most important project process begins at the end 23:11... need to 1st use a test app to verify the connection, before creating a new custom app... thanks.. 😉
What kind of data can be sent to the Bluetooth module? Just 1 and 0, or can it be any string? I see you're sending the string "1" and "0" rather than an integer, but I'd like to send text like "blue" "green" "red" - more options to the Arduino rather than Binary 0 and 1.
Hi Dvance, you can send any length of string. So it will work green, red, blue text. Bluetooth can handle good amount of data to transfer at high speed. To keep it simple in example project I just sent 0 and 1 otherwise code will be longer to extract string at Arduino side and then compare to take action. I hope this may help you. Good luck and best wishes1
Hi Oskar not 100% sure but you can check with datasheet of HC-05 Module online. I believe it will work with 3.3V as well. I hope this can help you. Thanks for your comment

Hi Jonny, if your mobile can detect Bluetooth of Bluetooth control box. Then probably its possible......but again you've to check with manufacturer of that control box. Otherwise, process remains same as explained in the video to use MIT App inventor to communicate with Bluetooth devices. I hope this will be useful. Good luck!!

Yes Manjunath, those video lessons are on the list. Hope I'll make it and share soon on RUclips Channel to cover all interfaces like WiFi, DC Motors, Servo Motors, Potentiometer etc with Arduino
Hi, in case of controlling multiple LED over Bluetooth. You must modify code for controlling multiple digital pins of Arduino and then modify Bluetooth App in MIT App inventor to add more buttons to send commands to control LED connected to Arduino using Bluetooth. I hope this information find useful to you. Good luck and best wishes!
WHEN explaining to beginners, you should perhaps mention that communication level of the this Module is 3.3 Volts and the communication level of Arduino is 5 Volts what could burn the module. Many comments here from people who play around with already 'DEAD' (??) ..Modules.

Hello! I tried your method but I face an issue with the LED not turning on! I even connected the resistor you proposed on the circut! Could you help me fix that issue, please?
Check your serial monitor on Arduino if you're receiving any data from Bluetooth APP. And also make sure connection between HC-05 Bluetooth module and Arduino is correct. Good luck and best wishes!
The resistor before LED will be current limiting resistor. This will protect your LED from high current flowing through circuit. Which can potentially burn your LED. Not very usual in case of Arduino but in many other circuit its good practice to use resistor before LED Protect. Thanks

Hi R4F, you need motor drivers in case if you want to drive hobby DC Motor and if you just want to control Servo motor. Then you drive without motor drivers. Bluetooth has nothing to do with motors. You'll be just sending data from HC-05 to rotate motors.
