This project uses a C8051 microcontroller development kit, an accelerometer evaluation board, and Simplicity Studio IDE—all from Silicon Labs—to rather quickly and easily build a motion-detecting alarm system.

Remote controls for electronics often use IR (infrared) radiation in a very precisely coded sequence for channel surfing, volume adjustments, and more. One of the most popular codes is the SIRC (Sony Infrared Remote Code) which may be used with a PICAXE microcontroller to manage a stepper motor, or most any other electronic or electro-mechanical device.

Tracking an infrared light source is not as difficult as you might think; a 14-pin PICAXE, a stepper motor with a driver IC, three phototransistors, and a few other components will do the trick.
