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 ...

Over at Tiny Transistor labs, [Robo] took it upon himself to reproduce the classic 555 timer in discrete transistor form. For bonus points, he also managed to put it in a package that’s the same basic ...

A monostable multivibrator is a timing circuit that produces a single output pulse when triggered. Using the 555 Timer IC in monostable mode, this project aims to design and simulate a circuit that ...

Generate a 0.5 ms pulse using a monostable multivibrator with a 555 Timer IC. Design an astable multivibrator and process its output through a differentiator and clipper circuit to trigger a ...

The circuit was designed sensitive enough to trigger and activate the alarm upon sensing wetness, moisture or dampness on its probes. 555 Timer – an 8-pin electronic device used in several mixtures of ...
