RC, RL and RLC Circuits The entire range of electronic components can be divided into two broad categories: active components and passive components. The Passive components include the Resistor (R), the Capacitor (C) and the Inductor (L). These are the three most used components in electronics circuits, and you will find them in almost every application circuit. These three components together in… |

Cycloconverters – Types, Working and Applications Power supplies can be classified into two broad categories: AC power supply and DC power supply. Since only AC power can be generated economically, most electrical machines run on AC power. However, the standard voltage and frequency from generating stations may not suit certain industrial machines. This is where power electronic converters like inverters and cycloconverters… |

Passive High Pass Filter Previously, we discussed the Passive Low Pass Filter; now it is time to look into the passive high pass filter. A passive high pass filter is an electronic circuit that allows high-frequency signals to pass while blocking low frequencies below a predetermined cutoff point. Same as before, if you look into the name, it shows “Passive”, “High… |

What is Thyristor and How it works? In general, Thyristors are also switching devices similar to transistors. As we already discussed, Transistors are the tiny electronic components that changed the world. Today we can find them in every electronic device like TVs, mobiles, laptops, calculators, earphones, etc. They are adaptable and versatile, but that doesn’t mean that they can be used in every… |

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. … |

Power Bank Circuit on PCB The features of the digital products are growing enormously which triggers the frequent usage of smart phones in several applications. Thus the battery backup time is getting decreased. It will be fun to build a Power Bank for Mobile Phone as spare charging source for emergency purpose which is also portable. Previously we have made… |

+12V and -12V Dual Power Supply Circuit The objective of this project is to convert 220V AC supply in to +12V and -12v DC supply, that is why it is named Dual Power Supply as we get positive and negative 12v power supply at the same time. This can be achieved in simple three steps: Firstly, 220V AC is converted into 12V AC by using simple step-down (220V/12V) transformer. Secondly, output of this transformer is given to… |

12v Battery Charger Circuit using LM317 (12v Power Supply) Most of our electronics projects are powered by a Lead Acid battery, in this project let us discuss how to recharge this lead acid Battery with a help of a simple circuit that can be easily understood and built from home. This project will save yourself from investing in a battery charger and help you to extend your battery life. So let's get started!!!! … |

0-24v 3A Variable Power Supply using LM338 Batteries are generally used to power up the Electronic Circuit and Projects, as they are easily available and can be connected easily. But they drained off quickly and then we need new batteries, also these batteries cannot provide high current to drive a powerful motor. So to solve these problems, today we are designing our own Variable Power Supply which will provide… |

Variable Power Supply By Arduino Uno In this tutorial, we will develop a 5V variable voltage source from Arduino Uno. For that, we are going to use ADC (Analog to Digital Conversion) and PWM (Pulse Width Modulation) features. Some digital electronic modules, like accelerometers, work on a voltage of 3.3V, and some work on 2.2V. Some even work on lower voltages. With this, we cannot get… |

Emergency Light An emergency light is an integral part of household electronics nowadays. We all know an Emergency light is used during a power failure to light up the home. As it is used during a power failure, it should last long, hence generally bright white LEDs are used in emergency lights, because they produce more light and consume less power. Emergency light is a very useful… |
