AC Phase Angle Control for Light Dimmers and Motor Speed Control using 555 Timer and PWM Signal Home automation systems are increasingly gaining popularity day by day, and nowadays it's become easy to turn on & off certain appliances by using some simple control mechanism like a relay or a switch, we have previously built many Arduino based Home Automation Projects using relays. But there are many home appliances that require control of this AC power rather than… |

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… |

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. … |

1 Watt LED Dimmer Circuit The LED DIMMER is primarily a 555 IC based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building a 1 Watt LED Dimmer circuit, first consider a simple circuit as shown in figure below. Now if the switch in the… |
