ATTN Smart People: relay shield v2.1 possible to use all four relays?
mixmaven 2013-08-10 19:22:30 3090 Views3 Replies Ok, newbie here but I cannot figure out how to utilize all four relays on the 2.1 board with an Arduino Ethernet board, is it even possible?
When stacked, I have to pull jumper IO 0 as it triggers relay 4.
It looks like the relay board uses 2, 7, 8, 10 and possibly the Ethernet board also uses 10, so am I out of luck?
If not, what are the jumper settings and some sample relaypin code please?
Thanks in advance.

To add to the response for those of us that need simple instructions (thanks to a very nice person named Dave that wrote me over the weekend) take the middle pin of IO 0/D10 and connect it to the green digital pin of your choice. For instance, I wanted 2, 7, 8, 3 so you can see in the photo below the correct jumper wire placement. The angle is a little off, but it is connected to the green bank, 3.
Hope that helps someone else.

Yes, the relay shield used pin 2,7 ,8,10 in default. But you can also choose other digital pins, just take off the small jumper caps of D10, and connect the middle pin header to other digital pins,so that you can use the four relays together with Arduino Enthernet shield.
