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.


Game interface

LEDs

Blue:correct position and number

Green: correct number, wrong position

Game Interface

Nine Numbers:

Four Reference Inputs

Four Guess Inputs

Input

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

Comparator

Comparator

  • Schematic of Comparator

  • EWB Simulation

    • 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.
