This is going to be very basic, and I have to apologize up front for even asking it. I'm not 100% this is the place to post this; however, I am hoping someone can help me out.
I have the Arduino Uno board and just picked up the Seeed Relay Shield. I quickly want to put together a project that will control a lamp with a motion sensor. I have the shield controlling a lamp successfully through programming; however, how the hell do I add in a motion sensor?
I know the shield is not using up all the ports; however, they are all plugged in eliminating the possibility of using the 5V, GND, and D3 port on the Arduino. I know I could solder wires, but I just want to test the thing out. Is there anyway to breadboard this sucker in there? What ports are used at minimum between a Seeed relay shield and an Arduino? I tried breadboarding my Arduino pin 7 to the shields D1 port, but I had no luck.
