This program is a MiniProject given in ECE 2035. This is to design and program the multiplayer ethernet based AGAR.IO mbed game. Starting code is given by the instructor to aid student to complete the project. It utilize uLCD, Accelerometer, pushbuttons, sdFileSystem, ethernetBreakoutBoard, speaker in mBED LPC1768. It uses the similar concept to the Game http://agar.io/
