Universal Gate NAND Logic Design - Voting Machine

The block diagram below represents a voting booth monitoring system. For privacy reasons, a voting booth can only be used if the booth on either side is unoccupied. The monitoring system has four inputs and two outputs. Whenever a voting booth is occupied, the corresponding input Booth A, B, C, or D is a 1. The first output, Booth, is a 1 whenever a voting booth is available. The second output, Alarm, is a 1 whenever the privacy rule is violated.

I learned how NAND and NOR gates worked and how their structure is placed using their diagrams. I learned even more about bread-boarding and how to test which areas of the Protoboard were broken using a continuity tester. I learned how to use the breadboard LEDs to test for voltage.
