Working quickly, Evan grabbed the Exacto Knife and many, many wires. He chopped away, cutting the rubber protection and somehow, the wire. All that was left behind were the dead, mutated remains of the blue wires.

Excited, Audrey got to work right away, experimenting with the lights and wires. A basic circuit was made, and after a few different tries, a parallel circuit was created.

Initial variables are identified as X, Y, and Z for the symptoms of coughing high temperature and low oxygen respectively. Based on the requirements set out on the truth table, the green light returns a 1 when all variables return 0. A yellow light scenario occurs where one of the three variable returns a binary 1 value. A red-light scenario occurs when 2 variables return a binary 1 value. The final alarm scenario occurs only when all three variables return a binary 1 value which means all defined symptoms are present.

We decided to draw the design of the processing unit first. Physically tracing scenario were more intuitive then using the circuit lab software directly. We then digitalized the final drawn version on circuit lab based on the requirements set out on the syllabus and blackboard.
