The purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...

This is a small size led flasher built with the 555 timer IC that is powered from 2 x 1.5V batteries. The circuit can be used as a flashing metronome, dark room timer, memo-reminder or other similar ...

This project demonstrates how to build a simple LED flasher circuit using the popular 555 timer IC in astable mode. The 555 timer generates a square wave output that turns the LED ON and OFF ...

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...

The objective of this project is to design and develop a simple and low-cost laser security alarm system using: A Laser beam and LDR (Light Dependent Resistor) to detect obstruction.A Unijunction ...
