I was wondering iff any1 had made a transmitter/reciever that used a single sender/reciever to send different signals.
E.g.
Four iput buttons that go through a series of circuts making them spark the sender an amount of time then on the other side it dissects it and flashs one of the four outputs...
Signal beem (ETRD mayby)

It would be pretty cool...

Nicely done. I noticed it takes two transmitters that means unreliable photons must be used... I'll try making a connection confirmer....
Great job
