[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 ...

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.

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 ...

The purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...

This 555 timer based circuit is a kind of voltmeter, also an analog to digital converter, that converts the analog input voltage to digital output pulses. The output pulse width is proportional to the ...
