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 stabilizer 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 controller 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 drawback 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 vending machine. About coffee vending machine: Read more…
Data Logger is a device that records data periodically with time and date which can be used in analysis of the system. In this article, we’ll make a solar data-logger. We will use Arduino UNO for this project. Memory card, Real Time Clock (RTC) will be used too. Lets start. Read more…
MPPT Solar charge controller is one of the most useful devices in solar power system. In this project, we are going to learn to make our own MPPT solar charge controller. Here we will use a synchronous buck converter and as a side option, we’ll keep Bluetooth datalogger and cell Read more…
In this article we are going to make a complete project with RFID. Many students made this project and submitted to their institute as their final year project. You can make this project for your final year project too. It will be a complete project for you. About this project: Read more…
