Sometimes, we need to add LCD with the project while the micro-controller itself has limited free pins for LCD. In that case, we can use shift registers to interface LCD with a micro-controller. After reading this article, you’ll be able Read more
Let’s make an Ammeter. Yes, in this article we are going to make an Ammeter for DC circuits. After reading this article you’ll be able to make one for yourself too. I hope it will help you a lot. So Read more
In this article, we will discuss DC Current measurement using Shunt. Measuring current sometimes becomes very necessary in electronics circuits. We can measure DC current using current sensors or by using simple shunt resistors. In this article, I’m going to Read more
In this article, we are going to learn how to make a high voltage AC voltmeter using Arduino and we are going to measure 2500V. Utilizing the technique shown here, we can even measure more than this range. So let’s Read more
In this article, we are going to measure high voltage using Arduino. Measuring over 1500V is not safe to work at all. But sometimes, we need to implement such a meter. Here in this article, we will make a high Read more
In this article, we will learn to make an AC voltmeter using Arduino UNO and 4×1 seven-segment display. If you learn this project clearly, you’ll be able to measure any AC voltage of your home. I hope you’ll make your Read more
A DC voltmeter is very common in electronics and needs to use in many systems as well. In this article, we are going to learn how to make a DC voltmeter with Arduino and Seven Segment display. If you learn Read more
I was looking for a good library to interface multiplexed Seven Segment with Arduino. But unfortunately, found no such good library that I can use as myself. Each one making trouble in Proteus simulation. Some examples I found over the Read more
Sometimes, we need to drive multiple displays in line. Sometimes we need to drive multiple numbers from one micro-controller. As micro-controller has a fixed number of pins so it is not possible to configure any circuit to drive 100 digits Read more
Like the high voltage AC meter, we can use the same Op-Amp circuit to measure high voltage DC voltmeter. In this article, we are going to learn how to make a high voltage DC voltmeter using a micro-controller and Op-Amp Read more
