Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

The design and build of a self-sufficient light source. Ideally powered by a wind turbine and controlled by an Arduino microcontroller.

This runs on an Arduino Mega 2560. There are only 15 PWM ( analog out ) pins so the head and front four tentacles have continuously variable RGB LEDs. The four remaining tentacles have 8 combinations ...
