Project Overview:
In this project, I simulated the generation of a voting machine for the Boeing Board of Directors, first identifying constraints and variables, generating a truth table, deriving a boolean algebra expression from that table, using a CDS to simulate my sketched out circuit from the algebra expression and eventually using a physical MyDAQ protoboard that would produce an accurate output for the voting machine. This project reaffirmed the most paramount principles of engineering: a thorough design process, documentation, and trial and error.

Flowchart of Design Process
This flowchart briefly explains my design process in sketching, simulating, and building a circuit applied to a voting machine and converts it into a function.
png2pdf (4).pdfVoting Machine Truth Table
Voting Machine Truth Table
I derived this truth table by assigning the members of the board to various variables and their votes as an input of "yes" for 1 and "no" for 0 and the output as "candidate chosen" for 1 and "candidate not chosen" for 0. The minterms represent every possible combination of votes that would result in the candidate being voted or an output of 1.

Unsimplified Circuit Sketch
Extracting directly from the midterms, I made an unsimplified, inefficient sketch of a circuit.

Final Circuit Sketch
I simplified the original Boolean algebra expression so that I minimized the amount of gates necessary in the creation of the voting machine circuit, saving precious integrated circuits.

Final Multisim Design
Following my final circuit sketch, I created the same design on CDS, making sure the outputs align with my truth table.
