Nathan Johnston / Mbed 2 deprecated Game_Controller_Project

Custom Game Controllers assembled in lab sessions and mounted with Nokia N5110 LCD display and a FRDM-K64F mbed plus various buttons, a joystick, potentiometer and piezo. Designed a game called 'Fruit Basket' to be played on the game controller where the player controls a basket and moves it catch objects that fall from random points along the top of the display to collect score.

Dependencies:   Basket Catch_Model Fruit Gamepad N5110 Objects mbed
