#792 555 Breadboard PWM Generator
A simple PWM generator circuit using the 555 timer IC designed for use on a breadboard.
Notes
It’s often useful to have a PWM square wave generator to use on a breadboard circuit, without having to deploy a full function generator.
This project adapts the basic LEAP#573 555 PWM Motor Control circuit and puts it on a small protoboard designed to plug into a breadboard.
Circuit Design
Designed with Fritzing: see BreadboardPWMGen.fzz.
