Motorola 68HC11 Project
The goal is the have four seven segment displays running through 0 – 9 digits. When a button is pressed once (so debouncing myst be taken care of) (What is Debouncing? http://www.bucketofmass.com/does-a-switch-really-bounce-debouncing/) the first digit stops. This continues until the last digit is pressed, at which time if three of the four displays have the same number, the text “Fun-” is displayed for short period of time. Then the program restarts again.
