The use of the ready-made RF module simplifies the construction of a wireless remote control system and also makes it more reliable. RF Transmitter This simple RF transmitter, consisting of a 434MHz ...

Makers, hobbyists and developers looking for a low powered Arduino compatible development board with built-in RF capable of running AVR projects for years using just a single AA battery.

Using an Arduino Pro Mini, a handful of buttons, and a standard TFT display, [Ricardo] has put together a serviceable little receiver with a fairly impressive user interface.

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.

The passive display contains a heatsink plate to dissipate heat build-up caused by operation in direct sunlight and is available with or without a module controller.
