I have to show that any kind of data is transferred from transmitter to receiver for my project. I have build a transmitter and a receiver (13.56 MHz) and I have an arduino uno. Its a simple project ( my guide says). I just have to demonstrate that something is being sent and something is received. Is it possible to use one arduino uno for both transmitter and receiver? Also any help on the codes will be highly appreciated. How and where (pins) should I connect Tx and Rx on arduino uno? Is it easier with two arduino unos? I have ordered another uno.
