RF transmitter and receiver

Help & Support Robot Parts
1

I have bought the seeedstudio 433MHz low cost transmitter/receiver pair RB-See-12. I don’t have experience with transmitters or receivers so I am wondering how to make a simple circuit with a button activating the transmitter and the receiver turning on an LED. I do have an arduino uno if it’s necessary to use that.

Hi Science4you,

Those modules are not aimed at controlling LED or trigger any I/O but transmit serial communication.
Attached is an example found online.

The “Seeedstudio 433MHz RF Long Distance” modules are made for that kind of thing.
