Re: Relay boards

Very bad news......
It's not working properly.
If i give it a direct command in the sudo window it switches relays on and off. I used the i2cdetect and it returns 20..

Re: Relay boards

Hi kind people, great news, I believe I have managed to get my Pi, mcp23017 and my relay working.... :o BUT it's looking like it's working backwards.....
If I give it..0x00 the relay lights come on
If I give it 0xff they all go off

Re: Relay boards

Hi Brandon 92, thanks for your reply. I'm now busy revising all the information you have given me. My relay boards are going to be 12v and the Pi will have it's own usb power plug.
