Introduction

This is my attempt to recreate the Christmas light, message wall from Stranger Things. This is a popular project on the Interwebs, but is usually done using an Arduino.

This project features:

  • A bare bones ATmega328 AVR (no Arduino ecosystem)

  • Command-line scripts to send tweets to the AVR over serial UART

  • Random flashes — to warn you when the Demogorgon is nearby
