## Cruise Control using Fuzzy MATLAB tool

Fuzzy Logic:           Designing a controller for non-linear systems is difficult. For conventional controller design we require mathematical  model and higher order differential equations. Some times we linearize mathematical model and design controller for system by applying well developed techniques for solving linear equations. But, as we know that real life […]

## Smart Energy Meter using Atmel AVR Microcontrollers

What is Smart Energy Meter? A smart energy meter is device which can calculate the energy consumption and send it to energy provider. It must be compact, cost effective and able to communicate data by itself with the power control center. I designed a smart energy meter through an ATmega8 microcontroller with following specifications: Compact […]

## 3 Phase Voltage Measurement using Atmel AVR Microcontrollers

3 Phase voltage measurement is a little bit tricky task. I will start from the basics and give you details step by step. Let’s start with the basics of 3 – Phase voltage. Specification of this Project: Measure voltage of each phase Measure angle of each phase Gives Line to Line voltage as well All […]

## What is the meaning of Home Automation

The word Home Automation has two parts i.e. Home and Automation. Home where one lives and automation originates from the word automatic i.e. to make things automatic. As an engineer we come across two types of automation: Home Automation Industrial Automation First we will take a fast look on industrial automation and then we will […]

## Basics of Some Solid State Switches

Switches are devices which allows the current in one direction and blocks the current in other. Solid state switches are devices made up of semi conducting elements with doping in them. Power electronics and most of the devices around us made up of these switching elements. They found application in every circuit of power electronics. […]

## What is Relay and How it Works?

A relay is just a simple switch with an electromagnet use to change the state of switch. As other switches come into types like SPST, SPDT, DPDT etc, in the same way relay has types like these switches. Moreover as they have electromagnet/current carrying coil inside with the addition of simple switch that’s why its […]
