MakerFactory Minecraft Java Adventskalender 2018 - my code
The original code can be obtained on http://bit.ly/mf-adventskalender-18-pc and is therefore not really closed source. So I included the original code here as well.
This is a maker project for using Minecraft 1.12.x and the AMI Arduino Minecraft Interface Windows application to control an Arduino Nano derivate through Minecraft.
