# Jack-o'-LED·trix ## Overview https://youtu.be/v3TM4u5AsgI 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: - [Adafruit Metro](https://www.adafruit.com/product/2488) - [Teensy-LC](https://www.adafruit.com/product/2419) - [Circuit Playground Express](https://www.adafruit.com/product/3333) - [Itsy Bitsy M0](https://www.adafruit.com/product/3727) - [Pro Trinket 5V](https://www.adafruit.com/product/2000) ![](https://cdn-learn.adafruit.com/assets/assets/000/063/653/medium800/hacks_IMG_1888.jpg?1539812511) ## Adafruit Parts ### Part: 12mm Diffused Thin RGB LED Pixels quantity: 2 You will need 48 pixels.
