We begin with the DC Motor H-Bridge Control project, which uses two 555 timers to create an H-bridge circuit that controls the direction of a DC motor, offering a great introduction to motor control.

Increase potentiometer frequency control span with a factor of 10 or more by wiring it up differently. This approach can also be used to extend the range of a pulse width/delay control. Example ...

The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you might ...

One of the most common clichés around here is that a piece of equipment chosen for a project is always too advanced. If a Raspberry Pi was used, someone will say they should have used an Arduino. If ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...
