Yes, the AC load can be dimmed or controlled using the PWM technique. PWM is Pulse-Width Modulation which is mostly used in DC circuits to control DC loads but if it is configured correctly, it can be used in AC load. In this article, we are going to see how Read more
This is a small article with a basic feature of LM555 or NE555 timer IC. This timer IC is very common and can be used in different circuits in different operating configurations. In this article, we are going to generate a PWM signal using NE555 timer IC. What is PWM Read more
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 that 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 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
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
