There are times you just want to build a project that can be controlled wirelessly e.g Robots, remote controlled cars, garage doors to mention but a few. Don't look any further. I give you the 315 MHz wireless remote control which is based on an IC PT2272. The wireless module is cheap and easy to use. The transmitter has 4 buttons which activates 4 pins on the receiver. These can be read with any microcontroller but for the sake of this tutorial, we'll be using an Arduino.
