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.

Thomas Gruber has introduced an app for the iPhone, iPod Touch and iPad that performs 555 timer circuit calculations and simulations. The app provides 10 different circuits, shows results in ...

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 ...

Sometimes the best inspiration is limitation. 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 ...

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 ...
