Wireless RF Remote & Receiver! Easy & Cheap! Great for Arduino and Raspberry Pi!

A review of Adafruit’s inexpensive RF keyfob remote and receiver. This is by far the easiest and least expensive RF solutions I’ve seen! It’s a “turnkey” solution – e.g. it works right out of the box. It can directly control things (like an LED or transistor) or be used to trigger a digital input pin on an Arduino or Raspberry Pi!
