Projects in Motion: Control Three Types of Motors with 555 Timers

With an estimated one billion 555 timers manufactured annually, you know this component must be versatile! We’re going to learn how to build and control drivers for three very different types of motors using a breadboard, resistors, diodes, transistors, and some 555 timers (along with a sprinkling of CMOS logic). These motor drivers are the […]

555 Timer Ball Whacker

This project uses a simple 555 timer chip and a feedback loop to control a servo-controlled wooden arm. Whenever an object comes close to a photosensor mounted on the end of the arm, it blocks the amount of light detected, which triggers the arm to swat the object away.
