Heart Shaped Serial LED Flasher Heart Shaped Serial LED Flasher

In this tutorial we are going to build a Heart shaped serial LED flasher circuit using 555 timer IC and 4017 IC. It is an interesting DIY which you can build for yourself or gift someone special to you. 

 

Required Components

555 Timer IC

Decade Counter IC 4017

Resistors - 220 Ohm, 1k and 10k

Capacitor - 10µF…

Police Light Circuit Flashing Police Lights Circuit

In this project we are going to design a circuit, to make a flashing light similar to that on a police car. This police light circuit is designed by 555 Timer IC and a decade counter IC. The timer here generates pulses which are fed to the 10-stage decade counter, the output of counter is so arranged to get a flashy lights as a police car.

Four Way Traffic Signal Circuit Project using IC 555 Timer Four Way Traffic Lights Circuit using 555 Timer IC

In this traffic light project we are going to design a circuit, to control traffic lights on a four-way signal. This circuit is designed by 555 Timer IC and a decade counter.  The timer generates pulses and these pulses are fed to the ten stage decade counter.

The ten stage DECADE COUNTER have a memory of TEN. It can count up to ten…
