Project Samples

This circuit will light a #194 lamp when the frequency of an input sine wave (from a function generator) is outside 1600Hz - 2400Hz (+/- 10%).   The circuit is operated on a single 13VDC bench supply, and the input waveform can vary from 10mV peak-peak to 30mV peak-peak. 

Only discrete BJTs were used in this project.

The goal of this project was to create a PID control loop that would center the laser on the solar cell provided. This project used two PWM signals into differential motor drivers to achieve a control system that seeks to center its signal.
