    Data sheet is needed for sure.

    The module says 5V tolerant, so I guess it works on 3.3V maybe? In that case you better lower the 5V of the PIC to 3.3V just to be sure that no problems may come up.

    Also the module will transmit when a change on input pins occurs. This means either when the switch is closed (grounding the input) or the switch is opened, leaving the input pin on the air.

    So you will have two transmissions and this is how the receiver will reflect transmitters status.

    P.S. By the way, do you get email notifications when there is a reply? I do not once again...
