Have you ever tried to design a variable regulated power supply? This article describes you how to design a variable power supply circuit . Till

In the previous post we have seen the circuit diagram of 9v battery charger circuit using LM311 and SCR .In this post let us see

A motion detector circuit typically employs a passive infrared (PIR) sensor or an ultrasonic sensor to detect movement in its vicinity. When motion is detected,

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

Introduction In this project, I will show you how to build a simple Light Activated Switch Circuit using LDR. Using this circuit, an electrical device

We usually turn ON the lights in our houses and offices manually. We need to turn ON the lights only when it is dark. So,

Automatic Railway Gate Control System is a simple but very useful project, which help is automatically opening and closing the railway gate upon detecting arrival

In this project, we will have brief discussion on how to interface 16×2 LCD module to AT89C51, which is an 8051 family microcontroller. We use

In this project, I will explain the circuit and working of a Random Number Generator using 8051 Microcontroller i.e. I will show you how to

In this project, I will show you how to build a simple Mains Operated LED Light Circuit, which can light up LEDs directly from the
