We know that the PWM signal is very easy to generate and we can control DC loads using this PWM signal. If we could use the PWM pulse to drive AC loads, the control circuit would become very easy. This Read more…
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 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 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 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 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. 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 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 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 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 Read more…
