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.

A PICAXE 08M2 can be used to read the amount of IR (infrared) light falling on a phototransistor and respond by moving a…

A PICAXE 08M2 can be used to read the amount of IR (infrared) light falling on a phototransistor and respond by moving a servo to a predetermined position.

We’ll continue our discussion of the C-BISCUIT demo bot by looking at portions of the RCB schematic that weren’t covered in the previous article.

In this article we’ll take a close look at two sections of the custom-designed control board for the C-BISCUIT demo bot.
