Bluetooth Smart Switch

Kod Sumber dan Mod Pin

Arduino UNO ke Mod modul Bluetooth Mod: RX pin 10 dan TX pin 11.

Kod:

#define relay1 2 // Relay IN1 disambungkan ke PinOut 2 Arduino

#define relay2 3 // Relay IN2 disambungkan ke PinOut 3 Arduino

#define relay3 4 // Relay IN3 disambungkan ke PinOut 4 Arduino

#define relay4 5 // Relay IN4 disambungkan ke PinOut 5 Arduino
