There’s no example sketch ( arduino) for the relay shield on the wiki. Which digital pins are in use by the shield, so that I can write my own?
Also, is there a breakout/solder point on the board for the additional pins not used by the shield? I need to use 2 pins as inputs.
1.The relay shield example sketch is already on the wiki under the resources catalog.
2.D1 to D3 are used.
3.Yes, there are several breakout/solder point on the board.You can take use of them.

Simon
