Bluetooth Smart Switch

Paglalarawan ng Bluetooth Smart Switch

Source code at pin mode
arduino uno sa bluetooth module pin mode: rx pin 10 at tx pin 11.
Code:
#include
Softwareserial Myserial (10, 11) ; // pin 10 = tx, pin 11 = rx bluetooth tx, rx
#define relay1 2 // relay in1 konektado sa pinout 2 arduino
#define relay2 3 // relay in2 konektado sa pinout 3 arduino
#define relay3 4 // relay in3 konektado sa pinout 4 arduino
#define relay4 5 // relay in4 konektado sa pinout 5 arduino
