Earth Pit Resistance Automation with GSM

What is Earth Pit? In EB system an earth pit refers to a pit dug in the earth with sand, glay and salt mixing. It is used to safety towards from short circuit current. This type of safety work prevent from current flows from high voltage to

Regulated Power Supply with Clock Pulse Circuit

The DC power supply is maintains the output voltage with respect of an alternating current (AC) mains voltage variations of load variations is called “Regulated Power Supply”. The regulated power supply consist of an ordinary power and voltage regulating deices like 78xx (Also called positive regulator) and

Proteus Software Tutorial

The Proteus 8 Design Suite software can interact the embedded projects with LED, LCD displays, and switches also interface with software sensors. In need of practical implementation of the projects circuits, we have to test with our C program and how it works or not. Proteus 8
