Relaxation Oscillator using Op-amp An operational amplifier is an integral part of Electronics, and we previously learned about Op-amps in various op-amp-based circuits and also built many oscillator circuits using op-amps and other electronics components. An oscillator generally refers to the circuit which produces periodic and repetitive output, like a sine wave or square wave… |

Design a Voltage Controlled Current Source Circuit using Op-Amp In a voltage-controlled current source circuit, as the name implies, a small amount of voltage across the input will proportionally control the current flow across the output loads. This current source circuit using an op amp is commonly used in electronics to drive current-controlled devices like BJT, SCR, etc. We know that in a BJT, the current flowing through the base of… |

Transformerless LED Driver Circuit for Reliable Low Cost LED Bulb Designs LED bulbs are said to be 80% more efficient than other conventional lighting options like fluorescent and incandescent bulbs. The fast adaption of LED bulbs is already noticeable around us and the global LED bulb market value has reached to around $5.4 Billion in 2018. A challenge, in designing these LED bulbs is that LED light, as we know works on DC voltage and the mains… |

DIY Arduino Power Supply Shield with 3.3v, 5v and 12v Output Options When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different sensors need different input voltage and current to run efficiently. In this scenario, a power supply which can output multiple voltages becomes very important. There are options… |

DIY Breadboard Power Supply Circuit on PCB A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a simple module. Most of the digital circuits or embedded circuits have a standard operating voltage of either 5V or 3.3V, so I decided to build a Power supply which can supply 5V/3.… |

Overvoltage Protection Circuit Protection circuits, like reverse polarity protection, short-circuit protection, and over/under voltage protection, are used to protect any electronic appliance or circuit from any sudden mishap. Generally fuse or MCB is used for overvoltage protection. Here in this circuit, we will build a simple overvoltage protection circuit without using a fuse. … |

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… |

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. … |
