Overview

Use a string of diffused pixels and a push button to create a new take on a jack-o-lantern sure to entertain trick-or-treaters and guests at your next Halloween party. 

This is a great beginner project if you're new to soldering or microcontrollers. You can use a real pumpkin (aka "cucurbita pepo") or a fake foam pumpkin (aka a "funkin") to create a reusable and unique piece of decor. 

I used an Adafruit Feather 32u4 Bluefruit LE board to drive the 3-pin pixels on my Jack-o'-LED·trix this year. The example code will compile on a number of different boards, including the following:
