Richard Ellingworth / Mbed 2 deprecated RobotRic

Version of Robotron arcade game using LPC1768, a Gameduino shield, a serial EEPROM (for high scores), two microswitch joysticks and two buttons plus a box to put it in. 20 levels of mayhem.

Abandoned writing serial EEPROM class and used Ser25LCxxx library instead. HighScoreTable class appears to be reading and writing correctly to EEPROM and high scores are displayed correctly.
