This Arduino lights dimmer project is based on Doug Hitchcock’s comment: “I need to have a lamp dimmer that can “cascade” from one lamp to the next (up to 4 lamps). Basically, when you close a switch, ...

The tutorial assumes you are at least familiar with C-lang-like language. It is not meant to teach anyone how to code in AVR/Arduino from scratch. It's more like a getting started for anyone who has ...

How to Build a Digital 220-V AC Dimmer with Arduino How to Build a Digital 220-V AC Dimmer with Arduino AC loads are everywhere around us because most home appliances are supplied with the mains ...

This program is useful for creating an energy-efficient lighting system that responds to motion, such as a hallway or security light, with adjustable brightness and automatic turn-off features after a ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
