Hi tom, tomorrow i will buy the arduino one R3 board, the 4 relay shield its out of stock on my local shop and i have to wait 15 days.

So in the mean time i will buy this relay module to practice: shop.dominioabsoluto.com/epages/2804864....64/Products/10000510

This relays module have 4 input conections (GND,IN1,IN2,VCC) and 3(output)x2(relays) connections (Normally Open, Comun, Normally Closed) (NO,C,NC)

But now i have some questions about connections from this relays module:

Reading the rolloff.ino.standard file:
// Define name to pin assignments
#define SWITCH_1 A0
#define SWITCH_2 A1
#define SWITCH_3 A2
#define SWITCH_4 A3

#define RELAY_1 4
#define RELAY_2 7
#define RELAY_3 8
#define RELAY_4 12

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?

Thanks,
regards
