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 device… |

IR Decoder for Multi-Speed AC Motor Control Single-phase alternating current motors are typically found in household items such as fans, and their speed can be easily controlled when using several discrete windings for set speeds. In this article, we build a digital controller that allows users to control functions such as motor speed and operating time. This article also includes an infrared receiver circuit that… |

Designing a True RMS to DC Converter using IC AD736 A True-RMS or TRMS is a type of converter which converts RMS value to equivalent DC value. Here in this tutorial, we will learn about true RMS to DC converter, how it works and how measurement methods can affect displayed results. What is RMS?RMS is the abbreviation of Root Mean Square. By definition, for alternating electric current, the RMS value… |

Understanding an Inductor and It's Working The inductor is one of the major passive components in electronics. The basic passive components in electronics are resistors, capacitors and inductors. Inductors are closely related to the capacitors as they both use an electric field to store energy and both are two terminal passive components. But capacitors and Inductors have different construction properties,… |

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… |

AC Circuit Theory (Part 3): Peak, Average and RMS Values These AC circuits series has taken us on a journey which has seen us discuss what AC really is all about, how its generated, some histories, concepts behind AC, its waveform, characteristics and some properties. Today we will be going over some terms and quantities associated with the Alternating Current. Peak Value of An AC Waveform… |

AC Circuit Theory (Part 2): AC Waveforms and their PropertiesAC Waveform
As established in the first part of AC Circuit Theory, when a magnet rotates around a coil or a coil rotates around a magnetic field, an Alternating current or voltage is generated. The rotation of either the magnet or the coil which leads to the periodic alternation in direction and magnitude of the Voltage (or current) leads to the generation of some sort of… |
