prana koirala / Mbed 2 deprecated ECE2036LAB3_FINAL

This program is done as an Lab assignment for ECE2036.

Dependencies:   4DGL-uLCD-SE PinDetect SDFileSystem mbed

Fork of mythermostat by jim hamblen

This program is a lab assignment to ECE 2036. It uses uLCD, pushputtons and SDCard via sdFileSystem. This is designed as a concept to train animal that could be used by biologist to determine if lemurs have a concept of numbers. uLCD is divided into two different rectangle. In each rectangle, program generate random shapes of different color. Pushbutton is used to select which side has smaller number of shapes. Each trial, result is stored in sdCard as datalogging.
