In this article, we are going to learn how to interface the DHT22 Temperature and Humidity sensor with the PIC16F877A microcontroller. DHT22 is related to DHT11 with some changes in data communication. This sensor is also known as AM2302/RHT03. As the Proteus library of DHT22 is not so available, so Read more
When you need to measure humidity, one sensor that comes to mind first is DHT11. This sensor also provides temperature data. Using DHT11, we can measure humidity and temperature but as it is a digital sensor, interfacing is not linear like an analog sensor. Here in this article, we are Read more
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 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 discuss DC current measurement techniques and different circuits for this 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
