What do these receivers work with? Basically, they are perfectly suitable with 434MHz transmitters, as well as their ability to fit in with the breadboard, and in order to create an easy yet helpful wireless data link they tend to work with microcontrollers.

However, notice that they work through one way communication. In order to act as receiver pair or transmitter pair; it is recommended to get two pair having different frequencies.

Note that both of the transmitter and receiver require common frequencies to work in, they also don’t have ID’s. The modules mentioned encounter noises in fair amounts. That’s exactly why filtering and pairing are so important, it’s the perfect method used to get rid of these annoying noises. Please check out the code below for more details, instructions, and information. Also, although they can be considered as being the same modules, the color of it might be blue or green.
