Introduction to Optocouplers Have you ever heard the word isolation, especially in electronics? As you might guess, isolation is a key factor when it comes to optocouplers. Isolation is sometimes mandatory and sometimes an extra feature in circuits. Optocouplers are used in many electronic devices, from mobile electronics to household electronics. So, in this… |

ESP32 based Temperature Sensitive Smart Fan Regulator Do you feel disturbed when you need to adjust the temperature? The wait is over, the solution is here! We often feel uncomfortable while sleeping due to certain changes in room temperature, but we don’t want to get up from sleep and regulate fan/AC due to lethargy. This hampers our sleep and may put a negative effect on our health. We will use Arduino… |

Simple Fan Regulator Circuit to Control the Speed of AC Fan A generic AC fan regulator circuit is essentially used to vary the speed of the fan. In this project, we will build our own fan regulator with minimum components and for better efficiency. Generally, the fan generates a humming noise when brought to use with different fan regulator circuits, our circuit uses DIAC and a TRIAC and produces minimum… |

New High-Temperature Snubber less TRIACs can Save Space and Boost Reliability STMicroelectronics' 800V 8H Triacs operate at full rated current up to the maximum junction temperature of 150°C, allowing heatsinks in drives for AC loads to be up to 50% smaller to combine compact dimensions with high reliability. Suited to industrial, personal care, smart-home, and smart-building applications, the new Triacs leverage ST’s… |

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… |

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… |

AC Fan Speed Control using Arduino and TRIAC WARNING!! The circuit diagram discussed in this project is only for educational purposes. Be advised that working with 220V AC mains voltage requires extreme precaution and safety procedures should be followed. Do not touch any of the components or wires when the circuit is in operation.
It is easy to turn… |

AC Light Dimmer using Arduino and TRIAC In our household, most of the appliances are powered from the AC supply such as Lights, TVs, and Fans, etc. We can turn ON/OFF them digitally if needed, using Arduino and Relays by building a Home automation setup. But what if we need to control the power of those devices for example to dim the AC Lamp or to Control the speed of the Fan. In that case, we have to use phase… |

What is DIAC: Construction, Working and Application in Triggering the TRIAC DIAC is a semiconductor device which has three layers and two junctions. The word DIAC consists of two parts, DI and AC. The DI stands for the diode (or two. Like Di, Tri, Quad, Penta etc.) and AC stands for Alternating Current. DIAC is the acronym of the diode for alternating current.
In the below image the DIAC… |

What is TRIAC: Switching Circuit and Applications Power electronic switches like BJT, SCR, IGBT, MOSFET, and TRIAC are very important components when it comes to switching circuits like DC-DC converters, Motor Speed Controllers, Motor Drivers, and Frequency Controllers etc. Each device has its own unique property and thus they have their own specific applications. In this tutorial we will learn about the TRIAC, which is a… |

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. … |
