Overview

The Close Encounters hat is a nod to the incredible movie -- with lights and sounds that mimic the mother ship, all stowed under the brim. A photocell triggers the action for GEMMA, while the NeoPixels and piezo buzzer provide the show. Get ready to change up that next kiss or rock a dark movie theater.
This guide was written for the 'original' Gemma board, but can be done with either the original or M0 Gemma. We recommend the Gemma M0 as it is easier to use and is more compatible with modern computers!
