RGB LED Lamp

This is a simple mood lamp which gradually changes its color according to HSV color model.

Build setup

1. Arduino Nano.
2. WS2812 LED strip.
3. Power supply (5V). Each RGB LED draws approximately 50 mA. If you have 20 LEDs, then you will need a 5V power supply capable of delivering at least 1A (and more is better).
4. Lamp. I took a cheap one, pulled out a socket, and replaced it with an Arduino wired to both LED strips and power supply (see photo above).

Example wiring

Arduino sketch

I had two LED strips wired in parallel, so I addressed both of them in led-lamp-sketch.ino file. You may change it for your needs. FastLED library is required for compilation.
