The function of the 555 timer is mainly determined by two comparators. The output voltage of the them controls the state of the RS flip-flop and the discharge tube. It also contains 3 working states.

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 ...

The project aims to create a PWM controller that contains a frequency range from about 170 to 200Hz to achieve a pulse width regulation featuring almost 0-100% with a relatively stable oscillator ...

This file type includes high-resolution graphics and schematics when applicable. Paul Rako, Creative Director, Rako Studios Back in 2011, Jeff Hamilton contacted Bob Pease, asking for Bob’s experience ...

It’s back! The 555 timer contest wants to see you do something cool with the 555 timer chip. At stake is the adulation of electronics geeks everywhere. Three top winners will be awarded a $150 ...
