Measuring over 1500V is not a safe 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 1500V. As assistive devices we’ll use Op-Amp and 4×1 seven segment display. Read more…
A DC volt meter is very common in electronics and need 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 voltmeter of 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 hot to make a high voltage DC voltmeter using micro-controller and Op-Amp circuitry. How to sense high voltage floating DC with Op-Amp? Like 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 higher easily with this circuitry. Before you read further, I’ll Read more…
After making a DC voltmeter in our previous post, you may looking for AC voltmeter. Yes, in this article, we’ll learn how to make an AC voltmeter using Seven Segment display and PIC16F73 micro-controller. Many people just make AC into DC using rectifiers and capacitors. But it is not a Read more…
A DC voltmeter can be used in many devices, even sometimes it become a must having feature for a device. In this article, we will learn how to make a DC voltmeter with Seven Segment and PIC micro-controller. What is voltmeter? A voltmeter is a measuring instrument which measures the Read more…
Seven Segment display is one of the most common LED/LCD based display which is used in many meters, clocks, info-display type devices. In this article, we’ll learn how to interface Seven Segment display specially that one which have multiple digits in one line. The other name of this type of Read more…
