A Temperature Controlled DC Fan is a system which automatically turns on a DC Fan when the ambient temperature increases above a certain limit. Generally,

Air flow detection is often necessary in many applications or systems where it is necessary to detect the presence of air to have a descriptive

In this project, we have built an Ultrasonic Rangefinder using 8051 Microcontroller and Ultrasonic Sensor. We have different ways to measure the distance. One way

Mosquito repellents like coils, mats, liquid vaporisers, creams are often used at various places. However they are prone to be fatal and can cause harm

The circuit which we have explained below is used to generate the output voltage whose magnitude is just double of the supplied input voltage. In

The circuit presented here is used to change the tune/melody into a different pitch level by devoid of loss in the tune. The characteristics of
