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 ...

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.

When it comes to the venerable 555 timer, Paul Rako agrees with Bob Pease—avoid using it if your application demands any kind of precision. Jan. 11, 2017 Back in 2011, Jeff Hamilton contacted Bob ...

Presented here is a Matlab program to design an astable multivibrator of desired frequency and duty cycle using a 555 timer. The aesthetic graphical user interface of the program helps you quickly ...

The 555 timer IC is an integral part of electronics projects. Be it a simple project involving a single 8-bit microcontroller and some peripherals or a complex one involving system on chips (SoCs), a ...

When it comes to designing timer circuits, the very first thing which comes to mind is the 555 timer IC. It’s the oldest piece of tech and thus you can rely on it blindly and best of all, it’s ...

〜難しそうに見えて実はカンタン。555タイマーで遊ぶ“最初の一歩”〜 この記事で分かること NE555タイマーが何をするICなのか（超ざっくり理解できる） LEDを1個チカチカさせる“基本回路”の作り方 LEDを2個“交互点滅”させる方法 ブレッド ...

Motion sensor circuits are there on the Internet for quite a while now. These circuits are mainly used to drive AC load (like… ...

[Bob] has been busy lately putting the finishing touches on three different projects that he plans on entering into the 555 Design Contest. His first entry is a low-power H-bridge, which can be used ...

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 ...

This project has a complete circuit for Police Siren. one can add the real siren sound in Proteus according to need. By using two 555 Timer ICs,the circuit outputs a clear stream of the police siren ...

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 ...
