The lead-Acid battery is one of the most common batteries used all over the world. In this article, I’ll discuss these lead-acid battery charging methods and we’ll see which method will be the most suitable for our battery. I hope this article will be helpful to you. So let’s start Read more…
We know that the PWM signal is very easy to generate using micro-controllers 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 is why many people look for PWM-based driver 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 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 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…
