We begin with the DC Motor H-Bridge Control project, which uses two 555 timers to create an H-bridge circuit that controls the direction of a DC motor, offering a great introduction to motor control.

2-10-2024 | First introduced in the early 1970s, the 555 timer integrated circuit is arguably one of the most popular ICs ever made. Rediscover the icon ...

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued ...

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 ...

A Digital fundamentals project worked on fire alarm detector circuit which is build mainly using 555 Timer IC and implemented in Tinkercad ...

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 ...

We discussed the breadboard circuit in video #190 (https://youtu.be/wcRuVxXlEKw), but here we have the finished product, including the panelised PCB from JLCPCB ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...
