Description of the task
Each student will design, implement, and test his own Digi-key system.

A remote control for your gate at home, your alarm system at home, or the access keypad for your dad’s company — they all make use of a digitally encoded key system.
This task will take you through the process of building your own small-sized “Digi-key” system.

The system is all about logic and logic gates. It can be split into two parts:

1. Entry Code — visitors’ access code combination.

2. Key Code — office’s secret code combination.

The two parts must be developed as one system. The two parts are connected through cables.
