These days, 433-MHz RF transmitter/receiver modules are very popular ... As you can see, the setup is on the Arduino ground with a 433-MHz receiver module and the USB interface. The code to capture ...

But if you have, say a receiver in a cabinet or ... That’s why some equipment now uses RF remotes. [Xtropie] used a pair of inexpensive 433 MHz RF modules to convert an IR system to RF.

[Reza’s] methodical investigation of this remote controlled outlet let him patch in with an Arduino using a 433 MHz transmitter ... straight for a wireless receiver he had on hand, using ...

In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to six relays and monitor two analog signals.
