This code controls two switches(via relays) using a bluetooth module.
Parts required to build this project
1.Arduino Uno
2.HC05 Bluetooth Module
3.Jumper cables/wires
4.Relay switch
5.Some food and cold drinks(LOL)
Basically the program sents a 'A' or 'B' to indicate its Power On or High state and 'a' or 'b' to indicate its power off or low state.
You will need to install a android app on your mobile. Install from here- https://iop.li/Wkw
