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, ...

An Arduino drives the switch-mode power supply, offering dimming thanks to PWM, and the ability to automatically switch the light on and off using an RTC chip with a battery backup.

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...

This translates into dimming and brightening of the light bulb. If you want to try this out using a resistor and an LED, here is a simple Arduino UNO Sketch that will dim and brighten the LED in ...

For example, if he’s watching a movie the lights will automatically dim, ... ATMega328 (Arduino Uno) has 6 PWM hardware implemented outputs and UART/I2C/SPI hardware modules, ...

The Arduino uses latitude and longitude to help decide when to click on the lights, so it's incredibly accurate. Otherwise, the build just includes an on/off switch, a Tiny RTC, a time adjustment ...
