And this is the code for the "receiver." It should take that message and put it in a byte variable where the switch statement decides what to do:
You can see in the receiver code I put my Serialprint functions before the switch statement to see what was being received. This is where I get an output of 0 if the button was pressed that is supposed to result in 1. If the second button is pressed and a '2' is supposed to be sent, the serial monitor shows 109
Please see attached.
