What is Bluetooth?          Bluetooth is short-range communication technology. The Bluetooth name is taken from the 10th-century Danish king Herald Blatant. Who combined Denmark and Norway.           Usually, when two electronic devices communicate with each other, they use cables, infrared rays, WiFi, etc. These are some of the […]

          A Multimeter is an electronic instrument, every electronic technician and engineer widely used a piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. It can also be used to test continuity between two points in an electrical circuit. […]

In an electrical circuit, a switch is used to turn the electricity on and off just like a valve is used to turn the water on and off. There are times when you want some water but don’t need all the water that the pipe can deliver, so you control water flow by adjusting the […]

          The LCD screen is an electronic display module, it can be used in a wide range of applications. The basic module of the LCD is a 16×2 LCD display and is very frequently used in various electronic circuits and well devices. Construction and Working Principle of LCD Display What is […]

STEPPER MOTOR Introduction to Stepper Motors           Like all motors, the stepper motors also have a stator and a rotor, but unlike a normal DC motor, the stator consists of individual sets of coils. The number of coils will differ based on the type of stepper motor, but for now, just […]

What is a Servo Motor?           A servo motor is an electrical device that can push or rotate an object with great precision. If you want to rotate an object at some specific angles or distance, then you use a servo motor. It is just made up of a simple motor […]

          An Ultrasonic sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. By recording the elapsed time between the sound wave being […]

Symbol:(q) Unit:    Coulomb (C) The fundamental electric quantity is charge. Atoms are composed of charge carrying particles: electrons and protons, and neutral particles, neutrons. The smallest amount of charge that exists is carried by an electron and a proton. Charge in an electron: qe = -1.602×10-19 C Charge in a proton: p = 1.602×10-19 C

Symbol: I Unit:   Ampere Current moves through a circuit element “through a variable.” Current is the rate of flow of negatively-charged particles, called electrons, through a predetermined cross-sectional area in a conductor. Like water flow. Essentially, the flow of electrons in an electric circuit leads to the establishment of current. I(t) =    dq/dt q: relatively […]
