Capacitor power supplies or transformerless power supplies are small but effective power supplies for small appliances like sensor boards, microcontroller boards, etc. This type of power supply is small in size, light in weight, and low in cost. Which can 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 Read more
To generate PWM(Pulse Width Modulation) both analog and digital circuits can be used. But using a micro-controller is much easier than other methods. To generate PWM, the micro-controller has a built-in PWM module. But if there is no such PWM 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, 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 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 Read more
In this article, we will understand SONY SIRC Protocol, and we will decode this protocol. Afterward, we’ll find out the command and address. Only after getting a clear idea, you can make your own decoder yourself. In this article, we 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 Read more
Max232 is one of the most popular RS232 communication ICs in the electronics arena. Straightforward circuit and very easy to use too. Anyone can implement the circuit within few minutes. But there are some issues I found in products. If Read more
One of the very useful transformerless power supplies using Viper12A IC can be used in many applications. It is sufficient to run micro-controllers, sensors, displays, relays, and so on. With very few numbers of components, we can get a reliable Read more
