Simple hardware and software techniques are illustrated in this project wherein 3 common 4-coil stepper motors are driven and controlled using a single Stamp II board.
The project aims to create a PWM controller that contains a frequency range from about 170 to 200Hz to achieve a pulse width regulation featuring almost 0-100% with a relatively stable oscillator frequency.
The goal of the project is to show how an IR remote control extender/repeater was built in order for electronic appliances from a remote location to be controlled.
