Crack The Code Safe Puzzle Box

This is an Arduino based Crack The Code puzzle box. You use a dial on the front to input a guess for the randomly generated code to the safe and 8 LEDs on the front of the safe then tell you how many of the digits you've guessed are correct and how many are in the correct place as well. Using this feedback and iterative guesses, you can work your way towards cracking the code and opening the safe.
