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.
