So, this is a quick project to allow you to set the RGB values with a simple hand-held gadget - maybe useful when working offline with these LEDs.
This project shows a WS2812b digitally addressable LED, but could be adapted for other LED types.
- An Arduino - clones can be found for $10
- An Adafruit LCD Shield - this shield has a 16x2 LED display, and 5 push buttons that we will use for changing the red, green, and blue color values. Adafruit also has a shield where the backlight color is an RGB LED - might be worth trying!
- An LED - this one uses a single WS2812b LED from a 30 LED/meter strip of LEDs - we had this left over from another project. Adafruit sells them individually on carrier boards too.
- Some solid core wire - I used some 20 gauge wire since it was rigid and held the LED nicely.
