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…
In our previous articles, we learned how to make an AC voltmeter and how to measure high voltage AC voltage. In this article, we will learn how to make a high voltage AC voltmeter. Yes, you can measure 500V+ or Read more…
Measuring high voltage AC is not safe just with a resistor voltage divider. Or sometimes, we can not connect one terminal to the GND of the measuring circuit. Sometimes, we need to measure a floating high voltage. In this article, Read more…
After making a DC voltmeter in our previous post, you may be looking for an AC voltmeter. Yes, in this article, we’ll learn how to make an AC voltmeter using a Seven Segment display and PIC16F73 micro-controller. Many people just Read more…
