Code
The code for HC-05 and Arduino Interfacing
c_cpp
This is the code you have to type into the Arduino IDE. The comments are not necessary, but I have commented heavily for better understanding, especially for people just starting out Arduino.

This is a brilliant project. However, I try to use HM-10 bluetooth device to do this project. However, I cannot pair HM-10 with my phone. The MIT app also fails to find the HM-10 unit inside the app. Any idea how to solve the problem? Thanks in advance.

Congratulations. Cute project with detailed instruction. The instruction is so nicely presented, and it also points out the common trap (char and int hints). Hope to see your Bluetooth controlled robot project soon and wish you very all the best.

After running this on breadboard, can it be done in real-time for a house that uses solar inverter?
