For large inductive AC loads, a soft starter is a very important circuit. A soft starter reduces the initial power supply to the load and potentially reduces electrical and mechanical shock to the device. Specially motors. The soft starter also reduces the spike in the initial current to any kind Read more…
A dimmer circuit is one of the basic circuits in power electronics people want to make. In this article, let’s learn how to make an AC dimmer circuit. In this project, we will use a PIC 12F675 microcontroller and a TRIAC as the switching device. Let’s start our AC dimmer Read more…
Data Logger is a device that records data periodically with time and date which can be used in the analysis of the system. In this article, we’ll make a solar data logger. We will use Arduino UNO for this project. A memory card, Real-Time Clock (RTC) will be used too. Read more…
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…
