This project demonstrates controlling multiple LEDs using a 74HC595 shift register driven by a 555 timer. The 74HC595 allows for efficient expansion of output pins, letting you control multiple LEDs ...

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.

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

Working with electricity can be a daunting and life-threatening task if you are a beginner in the electronic/electrical field, and things can go very wrong when electricity is not properly handled, ...

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 ...

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 ...

[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 ...

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 ...

I needed a quick calculator for my 555 timer projects. I got tired of dragging out the spec sheet and the hand calculator any time I needed to find the values for a frequency or a one-shot monostable ...

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 ...

A running joke we see in the comments by Hackaday readers whenever a project includes an Arduino or Raspberry Pi that seems like overkill is to proclaim that “I could have done it with a 555 timer!” ...
