In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

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 flip-flop.

A common problem with on-delay timers is the timing capacitor reset. Typical timers (555 included) rely upon both complete power loss and finite elapsed time to assure that the timing capacitor is ...

Use a 555 timer for power-on-reset that you find out does not really work because the 555 is, at its heart, a digital chip, and then the entire design cannot be shipped and all the bosses hate you.

The 555 timer chip, a staple in electronics, is known for its versatility in creating time delays, oscillations, and pulse generation. This iconic chip has been a fundamental component in ...

Advanced Linear Devices Semtech SX8122 The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit.

Hans Camenzind, the designer of the popular 555 timer IC died this week in Silicon Valley. He was 78. My condolences to his family and friends. Hans came to the U.S. from Switzerland in 1960.

He used a 555 timer that outputs a clock to the LEDs on the biz card, and placing a nine-volt battery on the terminals sets off the mini light show. See for yourself in the video below.

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 $15… ...
