In this article, we are going to learn about the solar charge controller. There are different types of solar charge controllers in the market. All these have different working principles. But the basic principle is the same. In this article, we will learn the basic principle of the solar charge Read more…
In this article, we are going to make our own remote-controlled device using SONY SIRC remote protocol. In the previous article, we have learned the basic pattern of this protocol and now we will use that in our circuit. We’ll use PIC12F675 micro-controller and mikroC Pro for the PIC compiler. Read more…
In this article, we are going to make our own control card for coffee vending machines. This machine is nowadays very common in shops and restaurants. Small businesses can be started with this machine. Here let’s make a simple functional control card for the coffee vending machine. About the coffee 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…
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…
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…
