LEDs are commonly used in electronic circuits, and with the LEDs, you can make many things which are interesting. You’ve probably seen many types of decorative lighting patterns-running lights, festival chasers, or rhythmic blinking effects that instantly stand out. This LED chaser circuit recreates that eye-catching style using a simple combination of the 555 timer…

Frequency Dividers are the circuits which divide the input frequency by n (any integer number), means if we provide some signal of frequency ‘f’ then the output will be the divided frequency ‘f/n’. Frequency dividers are very useful in analog as well as digital applications. Here we are building the circuit to divide the frequency by 2 or 4.

In this…

Have you ever feel a shock by touching the switch? It does not generally happen but sometimes physical contact with switches may be dangerous. But what if the switch gets wireless and you don’t have to press any button at all for switching on or off your home appliances. So today we are building a Simple Wireless Switch Circuit in which there is no need of physical contact…

You must have seen different kinds of decoration lighting patterns. In this LED chaser circuit, we have created an interesting LED blinking pattern by using a 555 timer IC and Counter IC CD 4017.

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.

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…
