ABOUT Arduino 4 Relay Bluetooth
CODE:
/*Relay IN1 connected to PinOut 2 ArduinoRelay IN2 connected to PinOut 3 ArduinoRelay IN3 connected to PinOut 4 ArduinoRelay IN4 connected to PinOut 5 Arduino--->you can connected to relay modul 4 channel
Serial data sending from Arduino 4 Relay.apkdata '1'-'4' to on is Ralay CH 1-4data 'A'-'D' to off is Ralay CH 1-4data '9' to on ALL CH 1-4data 'I' to off ALL CH 1-4*/
