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… ...

Just about anything can be made with a 555 Timer, and every circuit is fun to build, which I show in my book “ Essential 555 IC: Design, Configure, and Create Clever Circuits.” ...

When the Photo transistor receives IR rays, it conducts. The collector of the Photo transistor is connected to the trigger pin2 of a short duration Monostable timer built around IC NE 555. With the ...

A home-brew current transformer made from a split ferrite core and some magnet wire is the sensor, and a couple of op-amps and a 555 timer make up the detection and alarm part.

It’s basically a low-frequency, astable oscillator driving an active piezo sounder and built around the ubiquitous, eight-leg 555 timer chip. The BC547 transistor drives the astable oscillator (by ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

But the 555 just does not do anything precise, or even semi-precise, that I need done. So that's one thing I can "share" - my favorite circuit to use a 555, is: a blank piece of paper.

Ever wanted a 555 timer with complementary non-overlapping outputs. The XTR651 from X-Rel Semiconductor is just such a thing. Very similar to the good old 555, it includes a built-in 200pF timing ...
