In this article, we explore the process of interfacing the ID20LA RFID reader module with an Arduino board. You will learn about the basic working principle of RFID technology, the features of the ID20LA module, and the step-by-step guide to connecting it with an Arduino. Whether you are a beginner Read more…
In this article, we are going to learn how to make a simple voltage protector for your appliances. A small device can save lots of money, saving your appliances from voltage spike/surge/sag and unacceptable voltage range. So let’s make it! What is spike/surge/sag? Usually, your home supply voltage is either Read more…
This is a productive post with a voltage stabilizer circuit with 4 relays. A voltage stabilizer is sometimes becomes essential for our appliances if the supply voltage is not stable. Here in this post, you’ll find a product that can help you. Why do we need a voltage stabilizer? Our Read more…
In the previous article, we have seen how we can make an analog voltage stabilizer. We have seen that the circuit was pretty complex like a bird’s nest. In this article, we are going to learn how we can use a micro-controller for that purpose and make a smart voltage Read more…
A very common configuration of voltage stabilizers is using Op-Amp like LM324 and NE555 Timer IC. Before using any micro-controller this circuit configuration was used the most. Even still now, some companies are using this circuit where there is no digital display required. As because this design is easy and Read more…
In the previous article, we have learned about the basic operation principle of solar charge controller and besides, we have seen a working circuit with both analog and micro-controller based on/off charge controller. In this article, we are going to learn how to make a PWM charge controller using that Read more…
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…
Arduino is an open-source electronics platform based on easy-to-use hardware and software. This is also one of the most common and popular electronics proto-board with plug & play connectivity with Atmega328p micro-controller. But one of the drawbacks is you have to use the total board with your system or project. If 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…
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…
