Circuit Diagram

Watch this circuit diagram and follow my steps for make it

*First you want this type plastic case.

*Then cut the plastic case size of the bluetooth module. And input the bluetooth module after cut the box.

*Then cut the plastic case size of the 6 RC socket. And input the input the 6 RC socket after cut the box.

*Then you want 3.5 mm audio jack socket. 3.5 mm audio jack socket details you can see in this picture. Upper side pin is GND,  middle side pin is audio [L], and down side pin is audio [R].

*Then make a hole on the plastic case. And input the 3.5 mm audio jack socket.

*Then cut the plastic case as well as this picture. And input 2 MIC socket, 1 SPST switch, and 1 3mm LED.

*Then you want 7805 ic. 7805 ic details you can see in this picture. left side pin is 12 volt input,  middle side pin is GND, and right side pin is 5 volt output .

*Then attached the 7805 ic with the heat sink. And make a hole on the plastic case. then input the 7805 ic on plastic case.

*Then connect bluetooth module [+] wire on 7805 ic's 5volt output pin . And [-] wire connect to GND. [connect after watch the circuit diagram]

*Bluetooth module audio output wire connect to the Rc socket. Bluetooth module audio [R] connect to  Rc socket audio right pin, Audio [L] connect to  Rc socket audio left pin, and GND connect to ground. [connect after watch the circuit diagram]

*Then again bluetooth module audio output wire connect to the 3.5 mm audio jack socket. Bluetooth module audio [R] connect to 3.5 mm audio jack socket audio right pin, Audio [L] connect to 3.5 mm audio jack socket audio left pin, and GND connect to ground. [connect after watch the circuit diagram]
