In this post I will comprehensively explain 3 easy to build 10 watt power amplifier circuits, which can be built using discrete parts, such as resistors, transistors, and MOSFETs. The MOSFETs used in these designs are the ordinary IRF540 and IRF9540, that are easily avail;able in the market and are quite inexpensive. True Complementary 10 […]

Types of Power Amplifier Classes Explained in Simple Words
In this post I am going to explain power amplifiers and their classification according to their output electrical characters and application. We will be exploring amplifier classes: A, B, AB, C, D, E, F, G, H, I, S and T briefly and yes, that’s a lot of amplifier types that are available in today’s electrical […]
Simple Intercom Circuit [2 way]
The article presented below describes a very simple intercom system which can be built and installed at any required place very cheaply. The circuit utilizes just a single IC and a very few other components for the entire assembly. How it Works If you are looking for a simple and low cost intercom system for home installation, […]
How to Make a Simple Math Calculator using Arduino
In this post, I will show how to construct a calculator using Arduino, which can perform far complex arithmetical calculation than an ordinary calculator. Program: //——————-Program Developed by R.Girish—————// #include<math.h> float a = 500; float b = 105.33; float add; float sub; float divide; float mul; void setup() { Serial.begin(9600); Serial.println(“Simple Arduino Calculator:”); Serial.println(“n”); Serial.print(“a […]
Make this Simple Weather Station Project for Homes and Offices
In this post I will show how to construct an interesting Arduino based mini weather station project, which can show you ambient temperature, humidity, pressure, air quality and much more data from your surroundings, which can be used to predict weather from home. If you are interested in meteorology this project might come in handy […]
Simple Digital Water Flow Meter Circuit using Arduino
In this post I will show how to construct a digital water flow meter using Arduino and 16 x 2 LCD display. We will be taking a look at YF-S201 water flow sensor, its construction and working and how to interface with Arduino to extract some useful readings. The proposed project can measure the rate […]
