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 ...

The 555 timer has been a popular choice in electronics for a long time due to its versatility and wide range of applications. It can be used as a timer, oscillator, frequency divider, frequency ...

This 5-color LED flasher circuit can be built using the popular 555 timer and 4017 decade counter ICs. It does not require any expensive components like a microcontroller. The timer IC is used as an ...

What is the point of reviewing a cheap timer module, especially if it is based on the ubiquitous 555 timer chip? Recently I got an ‘updated’ version of the common 555 timer relay module. This time it ...

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...

If you are a hobbyist or have keen interest in electronics circuits, you must be familiar with 555 timer IC and its three popular circuits - Monostable multivibrator, Astable multivibrator, and ...

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 ...

Abstract: The 555 timer IC is a well-known integrated circuit having been widely used as a pulse generator. We propose a circuit containing a single 555 IC, an LED, an inductor, two capacitors, and ...
