im working on a home automation project and I want to use this relay shield
seeedstudio.com/depot/relay- … _134&r_q=q
to control lights and what not using XBEEs. I want this shield to be in another room and to be remotley controlled through an XBEE, without sitting on an Arduino.
I am using 2 XBEEs in API mode, using XCTU I have confirmed I can turn a LED on the remote XBEE on, but when I try it with the relay shield I hear the clicking of the relay but the LED does not light up, I have even used a volt metre on all terminals and there is nothing. wierd because I can hear the relays clicking, once when I send the command for remote xbee to turn pin on and again when I tell remote XBEE to turn pin off.
What am I missing ? why wont the LEDs turn on ?
