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 ...

This is a simple circuit which produces a sound similar to the police siren and is built using NE555 Timer. Two 555 timers act as an astable multivibrator. Here is the simple circuit designed to ...

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 ...

Save guides, add subjects and pick up where you left off with your BBC account. The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the ...

From simple buzzers to an Atari Punk Console, the simple 555 timer chip is the foundation of a whole lot of interesting lo-fi synth projects perfect for beginners. [Steven] put together a great ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC. In the process of making this circuit, we'll make a pcb design for it. This ...

Are you looking for a good source of information to get started into making and hacking electric circuits? We would like to refer you to Lessons in Electric Circuits. Even if you have good knowledge ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...
