Thank you to Ian for sending in his great running vest project! Read more here.
gemma.SMN is a sketch written for the Adafruit Gemma. It converts a (S)tring to (M)orse code, and blinks out the result via Adafruit (N)eoPixel strips.
The project came about because I wanted to replace the red, blinking LED that I attach to my reflecting vest when running at night. The light was bright enough, but I wanted more than the standard three blinking patterns.
The finished result is a set of three NeoPixel strips, powered by a 3.7v 500mAh Lipo that can blink a variety of morse code patterns.
Adafruit NeoPixel Digital RGB LED Strip – Black 60 LED – BLACK: You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, it’s 1.875 times as many but that’s within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticeable strip color – this strip has black-colored flex PCB, which will be less visible against black-painted walls. This is the strip with black flex PCB, it’s identical to the white 60 LED/meter except it has a different color mask on the flex strip. Read more.
