Here I am checking the output of 7812 regulator IC after connecting two 9V batteries in series to the input. After that the output is being used to

The popular 7812 regulator IC is a three terminal positive voltage regulator IC which provides a stable output. While 7805 IC provides a steady 5V DC output, 7812

Insulated Gate Bipolar Transistor (IGBT) is a semiconductor device that acts as a high-efficiency electronic switch for high-power applications. It combines the fast switching of a Metal-Oxide-Semiconductor Field-Effect

The choice between an inverted V and a horizontal dipole depends on your needs, as both are effective but have different installation and performance characteristics. An inverted V

Battery Management System (BMS) is a circuit that monitors, controls and protects rechargeable batteries. Aim is to ensure safety, efficiency and longevity of the battery. It monitors voltage,

We will go through the basics of Raspberry Pi Pico and see how it can be used to control a NEMA 17 stepper motor.

Simple initial steps in getting Arduino microcontrollers work for you. These can be tried out by anyone having an Arduino Nano.

Arduino group of microcontrollers are used in multiple applications, including the popular amateur radio transceiver micro BITX. I am describing my initial experience and simple experiments with Arduino

I have a 65Ah sealed lead acid battery, which I charge with my 180W monocrystalline PERC solar panel using a Pulse Width Modulation (PWM) charge controller. As part

While learning the basics of inverted V dipole antenna, we are asked to keep the ends of the antenna out of reach for humans and animals. The reason
