The 555 timer IC, originally introduced by the Signetics Corporation around 1971, is perhaps one of the most popular analog integrated circuits ever produced. In this new Elektor book, the focus is on ...

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.

[Bob] has been busy lately putting the finishing touches on three different projects that he plans on entering into the 555 Design Contest. His first entry is a low-power H-bridge, which can be used ...

The objective of this project was to design and implement a dual flashing LED circuit utilizing the 555 Timer Integrated Circuit (IC). The primary goal was to create a visually engaging effect by ...

This project has a complete circuit for Police Siren. one can add the real siren sound in Proteus according to need. By using two 555 Timer ICs,the circuit outputs a clear stream of the police siren ...

When it comes to the venerable 555 timer, Paul Rako agrees with Bob Pease—avoid using it if your application demands any kind of precision. Back in 2011, Jeff Hamilton contacted Bob Pease, asking for ...

In this project we build a boost converter circuit using a 555 timer IC. Boost converter is a non-isolated type of switch mode power supply that is used to step-up the voltage. In other words, it ...

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 ...

Editor’s Note: Hans Camenzind was selected for the Engineering Hall of Fame in our inaugural induction, which appeared in our 50th Anniversary issue in 2002. He died on August 8, 2012. His son, Peter, ...
