Controlling a Stepper Motor with an SIRC TV Remote and a PICAXE: Infrared Capabilities

Controlling a Stepper Motor with an SIRC TV Remote and a PICAXE: Infrared Capabilities

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.

Building an Infrared Tracker with a PICAXE 14M2 and a Stepper Motor

Building an Infrared Tracker with a PICAXE 14M2 and a Stepper Motor

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.


Designing a Circular-Touch-Sense User Interface

Designing a Circular-Touch-Sense User Interface

Controlling a Servo with a PICAXE and an IR Sensor

Controlling a Servo with a PICAXE and an IR Sensor

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.


Circular Touch Sensing with an EFM8 Microcontroller

Circular Touch Sensing with an EFM8 Microcontroller

In this project we will develop an algorithm for precisely locating a touch event that occurs somewhere on a circular capacitive sensor.
