I understand inputs relays module connections this is:
- Pin4 from arduino board go to IN1 relay module
- Pin7 from arduino board go to IN2 relay module
- GND from arduino board go to GND from relay module
- V5 pin from arduino board go to VCC from relay module
If i am right...My question now its... A0,A1,A2,A3 pins from arduino board, where should be connect in relays module?
