Communication Mediums of Smart Energy Meters Smart Energy Meters are the “Smart Meters” due to the only reason of some Communication medium present between the utility company and Energy Meter. Here I am not going to discuss the technical differences of the Communication Mediums of Smart Energy Meters instead the practical differences of the medium […]

## Millis Function of Arduino

What is Millis function of Arduino? A millis function of Arduino have a name of ‘millis’ because it calculates time consumed during the execution of code in milli seconds. Whenever you call the function in the code, it will give the total time consumed since the starting of the code execution till the calling of […]

## Wi-Fi based Smart Energy Meter using Arduino

Interfacing of ESP8266 with Smart Energy Meter using Arduino In this project, we are going to discuss that how to design a Wi-Fi based Smart Energy Meter using Arduino. Major focus of this article is towards the interfacing setup of Wi-Fi module (ESP8266) with Smart Energy Meter. I have already written a comprehensive article on […]

## Transformer Core Optimization using Genetic Algorithm

(This project is Transformer Core Optimization using Genetic Algorithm. Reader can take a quick introduction of Genetic Algorithm) Magnetic Core Optimization using Genetic Algorithm (GA) Problem Statement: For the magnetic circuit shown, a coil with 487 turns is wound on the left leg of the c-core with 3 Amperes current supplied to it. Assuming the […]

## Introduction to Genetic Algorithm (GA)

Genetic Algorithm (GA) Genetic Algorithm has turned out to be excellent optimization tool. It does not require an exact mathematical model of the physical system. Furthermore, speed and robustness are prominent properties of this scheme. The proposed design strategy for optimizing the transformer core parameters is based on GA. It is a stochastic search algorithm […]

## Mathematics Matrix Manipulation in MATLAB

This article is simplest guide for matrix manipulation in MATLAB which a programmer need for a regular work. Everything is treated as a matrix in MATLAB. Ex- a=1; which is a scalar means a matrix of one row and one column which contains the element ‘1’. You can read this in article an introduction to MATLAB Matrix […]
