Warning: I’m fairly new to electricity concept and Spark.
I’m trying to build a remote Wifi socket with the relay shield along the Spark core. I want to control 2 outlets each plugged in their single relay (socket 1 to relay 1, socket 2 to relay 2). The current needs to be plugged in there somewhere. Where do I plug the positive and negative wires into the relay? Then, how can I relay the current to each of the sockets (I don’t quite get the difference between COMM and NOCOM, etc.) Can the Relay passes the electricity from relay 1 to relay 2?
Thanks for your help.
