Overview

This project implements a 2 player Rock Paper Scissors game on 2 mbed microcontrollers. The hardware components used in addition to the 2 mbeds are:

• 2 uLCD-144 G2 128 by 128 Smart Color LCD display boards with serial interfaces
  • Purpose: To display:
    • The name of the game
    • Push button options
    • Prompt to begin game
    • Time left for each player to choose an option
    • Option to continue or end the game

• 6 parallax push buttons (3 for each player)
  • Push button 1 represents ‘Rock’
  • Push button 2 represents ‘Paper’
  • Push button 3 represents ‘Scissors’

• 2 Shiftbrite LEDs
  • Increases the intensity of light as player gets closer to running out of time

• 2 SD card readers
  • To play a sound file every time a button is pressed and when the game ends

• 2 speakers

How the game works

• Both players are prompted to press a pushbutton of their choice in a time span of 5 seconds. [Note: If a player times out, they are given the option to try again]
• Once a player pushes a button, it waits until the other player pushes a button as well.
• Once both players choose an option, they are shown what option the other player chose, who won and what the current score is. They are then given an option to either continue the game or end it.
• If both players choose to continue, the game starts again, keeping track of the previous score.
• If one of the players chooses to end the game, the game ends with a display showing which player ultimately won.
