This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

This repository contains the implementation of a Smart Street Light Control System using a 555 Timer IC, Light-Dependent Resistor (LDR), and a Relay. The system uses an LDR (light dependent resistor) ...

Here’s your useful and beautiful circuit for the day — [New Pew]’s vibration sensor takes manual control of the flip-flop inside a 555 timer and lights an LED in response. Use it to detect those ...

This circuit enables the on/off times of a 555 timer to be independently varied over a wide range. This is not possible with a conventional 555 circuit with the RC network being charged from the ...

This project presents a low-cost, educational traffic signal simulation system based on the 555 timer IC in astable mode. Designed to model the standard green-yellow-red sequence found at road ...

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, ...

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 ...
