Push-Pull Amplifier Circuit Circuit schematics are crucial for electronics engineers to understand. For the majority of real-world applications, Class A amplifiers offer the lowest distortion, Class B amplifiers the most efficiency, and Class AB amplifiers the best resolution. The particular needs for power, distortion, and efficiency will determine the choice. A push-pull… |

Darlington Transistor Pair Darlington transistor is invented in 1953, by a US electrical engineer and inventor, Sidney Darlington. Darlington transistor uses two standard BJT (Bi-polar junction transistor) transistors which are connected together. Darlington transistor connected in a configuration where one of transistor’s emitter provides biased current to the other transistor’s base. … |

Optocoupler: Its Types and Various Application in DC/AC Circuits Opto-coupler is an electronic component that transfers electrical signals between two isolated circuits. Optocoupler also called Opto-isolator, photo coupler or optical isolator. Often in circuits, especially low voltage or highly noise sensitive circuits, Optocoupler is used to isolate circuitry to prevent electrical collision chances or to exclude… |

RC Phase Shift OscillatorWhat is Oscillator?
An oscillator is a mechanical or electronic construction which produces oscillation depending on few variables. We all have devices which need oscillators, traditional clock that we all have in our home as a wall clock or wristwatch, various type of metal detectors, computers where microcontroller and microprocessors are involved all… |

Simple Lie Detector Circuit using Transistors Electronics has always been fun to play with, once we learn the very basics of how each component works and how to use them in our circuit it’s fairly easy to design, simulate and fabricate our ideas into a PCB. In this project let’s build a simple fun circuit, analyse it and then fabricate a PCB to improve our learning curve. The concept behind this Lie Detector Circuit is… |

Arduino Relay Control Tutorial LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will use an AC bulb instead of a normal LED and will blink an AC bulb. You can also drive into this project of Relay Interfacing with PIC Microcontroller. … |

Different Types of Transistors and Their Working As our brain is made up of 100 billion of cells termed Neurons which are used to think and memorize things. Like as computer also have billions of tiny brain cells named Transistors. It is composed of chemical element extract from sand called Silicon. Transistors change the theory of electronics radically since it has been designed over half a century before by John Bardeen… |

IR Remote Controlled TRIAC Dimmer Circuit In this project, we are going to make a TRIAC dimmer circuit for AC Appliances. Here we are not going to use a microcontroller. We have used basic components to complete this task. In this project, we will use Triac to control the brightness of the AC bulb with a IR TV Remote. You can also control Fan speed with your TV remote using this Triac Dimmer circuit. … |

PNP Transistors The first bipolar junction transistor was invented in 1947 at Bell laboratories. “Two polarities”is abbreviated as bipolar, hence the name Bipolar junction transistor. BJT is a three terminal device with Collector (C), Base (B) and Emitter (E). Identifying the terminals of a transistor requires the pin diagram of a particular BJT part. It will be available in the datasheet.… |

Transistor as an Amplifier Circuit Transistors are the semiconductor devices used for switching or amplifying electrical signals. They are highly durable, smaller in size and operates on a low voltage supply. A Transistor is a three terminal device: Base: This pin used for activating the transistor (minimum 0.7V required to turn ON a Transistor) Collector: Current flow through… |
