Introduction to microprocessor controlled electromechanical systems. Interfacing sensors and actuators to computers, electrical and mechanical prototyping, dissection of commercial product. Final term ...

Building a simple circuit with 39 transistors, 31 resistors, and a handful of diodes is a good introduction to digital electronics, and after two attempts, [spencerhamblin] knocked it out of the park.

This Digital IR Theremin creates tones based on the distance of an object from its IR sensor. There’s no microcontroller here, since the project is part of an Introduction to Digital Electronics ...
