In these days of cheap microcontrollers, it is hard to remember there was a time when timing things took real circuitry. Even today, for some applications it is hard to beat the ubiquitous 555 timer IC. It is cheap, plentiful, and reliable. What’s interesting about the 555 is it isn’t so much a dedicated chip as a bunch of building blocks on a chip.
You can wire those building blocks up in different ways to get different effects, and [learnelectronics] has a video showing the three major modes you typically…The post The Three Faces Of The 555 appeared first on FeedBox.
