Blinky Love Note

I made a blinky love note for my sweetheart this Valentine’s Day, because what’s more romantic than Morse code?

A single LED paints a 6″ x 6″ canvas with light. It first tells a story through color, and then slowly pulses a secret message in Morse code, fading from deep to light pink.

The smart LED is run from a 5v Adafruit Trinket, powered by 4 AA batteries. Download the code here. (This just blinks “hello world.” The secret message will remain secret).
