Understanding How a Single Channel Relay Module Works and How to Use it with Arduino to Control AC Loads A single-channel relay is an electronic switch that can be controlled by a low-power electrical signal, such as the output from an Arduino microcontroller. By using an Arduino Uno and a single-channel relay module, you can control high-voltage or high-power devices, such as lights, motors, and appliances, from your computer or mobile… |

IoT Based AC Fan Speed Control using Smart Phone with NodeMCU and Google Firebase In this article, we are building an AC Fan Regulator Circuit, which is able to control the speed of the fan by restricting the flow of current to the fan. The term AC Ceiling Fan Regulator is a mouthful, hence we will simply call it a fan regulator from now on. A fan regulator circuit is a crucial component that is used to increase or decrease the speed of an AC Fan/motor… |

Building a Compact and Low Power Solid-State Relay to Control AC Home Appliances using ESP8266 for IoT Applications Relays are common in many switching circuits where controlling (turning ON or OFF) an AC load is required. But due to the electromechanical characteristic, a mechanical relay has a self-life, and also it can only toggle the status of the load and cannot perform other switching operations like dimming or speed control. Apart from this, an electromechanical… |

All About Transformer Protection and Transformer Protection Circuits Transformer protection is crucial as transformers are one of the most critical and expensive components of any distribution system. It is an enclosed static device usually drenched in oil, and hence, faults occurring in it are limited. But the effect of a rare fault can be hazardous for the transformer, and the long lead time for repair and replacement of transformers makes… |

230V AC LED Driver Circuit for Powering 2.5Watts LED Light AC LED driver circuits are overly popular due to the advancement of High current white LEDs. We already made a Transformerless LED driver circuit previously, but in that circuit, we used a dedicated LED driver IC like LNK304 to generate 13.6V 150mA of output current to power LEDs. But in this tutorial, we will not use any dedicated driver ICs, but we will make a 2.5 Watt AC… |

AC Lights Flashing and Blink Control Circuit Using 555 Timer and TRIAC Sometimes, we might need an AC bulb flasher circuit that can blink a series of bulbs in a particular time interval for decorative purposes. By controlling the flashing time interval and sequence, we can make a series of bulbs look beautiful for outdoor decoration in Cafeteria, Restaurants, etc. or even used it for heavy Christmas light decoration, so here I have shared a… |

Half Wave and Full Wave Precision Rectifier Circuit using Op-Amp A rectifier is a circuit that converts alternating current (AC) to Direct current (DC). An alternating current always changes its direction over time, but a direct current flows continuously in one direction. In a typical rectifier circuit, we use diodes to rectify AC to DC. But this rectification method can only be used if the input voltage to the circuit is greater than… |
