[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 ...

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 ...

Anyone who has designed circuits using the 555 timer chip will, at some time have wished that it could be programmed for longer timing periods. Anyone who has designed circuits using the 555 timer ...

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use ...

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 ...
