Lab 1: From left, Bank Vault access panels (A,B,C). Our 2 access codes are 1000 (small) and 1100 (big). 

Vault opens when 2 stations are accessed by *separate users*. It opens for: Big Small X, Big Big Small, and Small Small Big, but NOT for BIG BIG BIG, or SMALL SMALL SMALL. This is the bottom pathway from the access panels section.

The top pathway and furthest right, detect which stations are being accessed by who, how many, and implements an LED counter to determine the number of correctly accessed stations.
