project specification
Project Specification
  • Digital Mastermind is a game that enables the user to guess a combination of four decimal digits, translated into four binary bits
  • Output shows a series of lighted bulbs each signifying a combination of correct number and position of the keyed guesses.

LEDs

Blue:correct position and number

Green: correct number, wrong position

Game Interface

Nine Numbers:

Four Reference Inputs

Four Guess Inputs

Input
  • Schematic of Input to Memory
  • Electronic WorkBench EWB Simulation
    • To simulate please press space once then B twice then put to low one of your inputs, press space, twice B, then input. Repeat last two steps until the last LED in the Serial-in-Parallel-out is lighted.
    • First four inputs are for the Reference code
    • Last four inputs are for the Guess code
    • This simulation should be done with an EWB Software
    • Open File input2memory.ewb

    • Given the Reference input 0 (1111), 2 (1011), 8 (1110), 4 (1101). Inputs refer to the truth table of 74LS147
    • Given the Guess input 2 (1011), 2 (1011), 8 (1110), 7 (0001).
    • Press 1 twice then if LED lights up, the two numbers compared at that time are different.
    • To finish all 16 comparisons, press 1 twice until all LEDs in the binary counter outputs light up.

  • Schematic of Serial to Parallel Output
  • EWB Simulation
    • Press C twice and then 1 twice
    • Repeat until the binary counter reaches its maximum count (Don’t Forget to Press CC after this!)
    • Blue LED correspond to right number, right position
    • Green LED correspond to right number, wrong position
    • For the given code(see comparator) the output has two blue LEDs lighted up.
