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
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
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, we are going to learn how to do that floating 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 make AC into DC using rectifiers and capacitors. But it Read more
A DC voltmeter can be used in many devices, even sometimes it becomes 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. So let’s make our DC voltmeter using PIC16F73 and mikroC coding. What Read more
Seven Segment display is one of the most common LED/LCD-based displays which is used in many meters, clocks, info-display type devices. In this article, we’ll learn how to interface the Seven Segment display especially that one that has multiple digits in one line. The other name of this type of Read more
