Hi all,
I'm using some 433Mhz rf modules for a project, I would like to ask, is it necessary to use decoder/encoder if I only need 1 channel signal to be sent and received. ( which mean i only need 1 data line, instead of 4 ) Can I input directly to the input of transmitter and use the output of the receiver to switch on an LED?
