In this article, we will see different LED Running Lights Circuits, which are also called as LED Knight Rider Circuit. These circuits can be employed

Introduction In this project, I will show How Speed Control of DC Motor can be implemented using 555 and Pulse Width Modulation (PWM). We use

Introduction In this project, we will see a PWM based LED Dimmer using 555 Timer IC. The main principle of this circuit is to generate

In this project, I will show you how to design a simple Police Siren Circuit using NE555 Timer IC. I will also share with you

The Touch ON and OFF Switch Circuit is built around a 555 timer by making use of the default properties of the Pins of the

Many electrical and electronic appliances require DC or AC power for their operation. While AC power is made available mostly through AC supply mains, DC

Have you ever heard about dummy alarm? This is similar to the alarm but this flashes high power Red LEDs for every 5 seconds. This

This circuit protects the costly equipment like TVs, air conditioners, Refrigerators, etc. from high voltages as well as low voltages. If the supplied voltage is

This circuit is designed to alert the user when an intruder enters into the home. If there is any obstacle in front of IR sensor,

Have you ever tried to design a circuit that produces sound? Here is the circuit that produces five tones. This is a simple toy piano
