The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you might ...

The 555 timer in bistable mode is also known as a flip-flop circuit. A flip-flop circuit alternates between two stable states, in this case the output of electrical current from the output pin. Unlike ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

The 555 timer IC, originally introduced by the Signetics Corporation around 1971, is perhaps one of the most popular analog integrated circuits ever produced. In this new Elektor book, the focus is on ...

The NE555 is a popular IC that functions as a timer or an oscillator. It’s an 8-pin IC available in various packages. We are using an SOP-8 package of the IC. Due to the versatile functioning of the ...

Over 1,000+ students have already grabbed this course for free — don’t miss out! Are you fascinated by electronics and want to dive into the world of circuit design? The 555 timer IC is a cornerstone ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

Many of us could sit down at the bench and whip up a 555 circuit from memory. It’s really not that hard, which is a bit strange considering how flexible the ubiquitous chip is, and how many ways it ...
