Team 3 Final Project

Minecraft Controller 

My controller is designed for the game Minecraft. It is in the shape of a pickaxe for thematic purposes.

The pickaxe is the main tool you will use in Minecraft, as it involves mining. I decided to make the controller

a diamond pickaxe. To input your button presses, you must tap the head of the pickaxe on the table while pressing

a button. This is to signify doing an action in the game, similar to doing a similar action in real life. It also has

a joystick on the back to allow movement. The feedback on the controller is when you strike the table to cause

an action. The pickaxe has an end that naturally draws players to use it like a pickaxe. Tilting the head of the

pickaxe in any direction will cause the player to look around the screen. To achieve this, we used the

accelerometer in the Circuit Playground Express. This is intuitive and adds more action to the controller than

a mouse would. I wanted to make every button and analog fit on the handle of the pickaxe to be easy to reach

everything without adjusting, and while moving. I also planned to put lights on the pickaxe to add more feedback.

I may do this in the future.
