Hi,
I have the RelayShield v2.1 and using the Ardunio Ethernet board. I have the code modified and the Ardunio board programmed. I have tested with the door open/close function using COM1 and COM2. The instructions were really clear on how do that. What I am struggling with is how to connect the door sensors to the RelayShield v2.1. I am not sure what pins to use and actually how to physically connect the wires from the sensor to the RelayShield v2.1..
thanks
