Minecraft is a very popular game and it is also one of the most played games. I have built a Mini Keyboard which is dedicated to play Minecraft! All you need in order to build this is an Arduino Leonardo, Due or Micro board and some basic hardware. This is a quite easy and straight forward build as it only consists of basic components.
You can grab a copy of the code from my website and as well as some tips and the schematic.
An Arduino Leonardo, Due or Micro board
9 Tactile Switches
9 10k Ω (ohm) resistors
Some hook-up wires (Male to Male)
