Basic Electricity is the presence of motion of electric charges. Electricity is all around us powering houses, offices and technologies like our cell phones, computers, lights, soldering irons, and air conditioners. We can’t imagine this […]
Using an Attiny85 microcontroller is an attractive and economical way to build a minuscule Arduino project backed by a few lines of code. Very often such a project will demand an external adapter to program […]
As you all know that an electric conductor has free electrons inside them, due to movement of these free electrons, current is produced and when we give them energy via connecting battery, the electrons move […]
Electron current and conventional current are two types of notation we use to mention current flow in a circuit. These two notations are opposite to each other. We need a notation to do some calculations […]
Electricity is a great gift science that has given to mankind. We use electricity almost all the time and it has been a part of our modern lifestyle. We can’t even imagine our lives without […]
Recently I got an unusual query from a newbie microcontroller hobbyist on how to drive an electromagnetic relay using a bipolar junction transistor (BJT). Admit it, analog electronics is not a piece of butter cake […]
Wearables and dozens of real time applications use a microcontroller other than a microprocessor for their core design of the entire product. And, these days almost every electronic device comes with a microcontroller. Most of […]
Here’s a little idea to monitor the level of water in a water tank with the help of an ultrasonic sensor module. The build process is very simple, and best understood by referring to the […]
Let me introduce another minimalistic circuit of a simple Selfie light based on generally available low-cost components. The idea presented here is a compact USB chargeable design with inbuilt rechargeable battery and dedicated battery charger […]
Let me start this month with a Solar LED Road Stud project. Solar LED road stud is a self-powered, autonomous device usually installed on the center line of a road, the lane boundary, and crosswalks […]
