Built by Wolves for Wolves


EE195 Final Project:

A PowerPoint presentation was done on the LM555 timer.

For the display model, I built a simple Pulse Width Modulator (PWM)


This is the linear taper potentiometer that was used to very the pulse width


During the presentation, a 6 volt light bulb was connected to the output and its brightness varied, as well as a motor's speed and a laser.

The laser when swiped across the room, actually displayed the pulse widths varying.
