These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

[Reza’s] methodical investigation of this remote controlled outlet let him patch in with an Arduino using a 433 MHz transmitter ... rigs that have multiple modules to control many devices.

433 MHz radio signals are all around us ... [Joonas] first explores using an Arduino to do the job, paired with a RFM210LCF-433D radio receiver module. This setup dumps out data to a computer ...

This Arduino module takes past circuits and codes, and applies them to a new program called Snap4Arduino. Snap4Arduino allows us to program an Arduino board in an environment similar to Scratch, which ...
