When you are working with electronics, especially power electronics you must have to measure line frequency. But in most cases, people do not have a frequency meter. If you knew how to make a frequency meter in a very easy way, you would make one for yourself. Here in this Read more…
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 to do that yourself. It’s easy! So let’s start Interfacing 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 let’s start our DC Ammeter with PIC16F73 microcontroller. What is 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 start our High Voltage AC voltmeter. High voltage measurement technique: 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 voltage DC voltmeter with Arduino UNO that can measure over 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 own AC voltmeter using Arduino now. What is the difference 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 this carefully, you’ll be able to make a voltmeter of 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 internet, not explained properly or not simplified at all. That 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 or even more 7-Segments. That is why we need to 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 circuitry. How to sense high voltage floating DC with Op-Amp? Read more…
