Project 4.1.3 State Machine Design: Tollbooth (VEX-DMS)

Your technical report will be written in MS Word and should include the following:

Introduction/Purpose of Project-

The state machine that I designed is based on the tollbooth gate example. In this design, I was required to use a PLD to create a functioning prototype.

Explanation of Operation-

The operation was to design a state machine that will control the opening and closing of a tollbooth.

Explanation of Build-

The build includes constructing a VEX tollbooth by following the given pictures and diagrams from PLTW. A DMS board was then wired by following the Multisum PLD I built.

Explanation of Testing-

To test the operation, I transferred the Multisum circuit to the PLD to enable the tollbooth to open and close.

Conclusion-

There was a few bumps in the road when I transferred the PLD to the DMS, but after fixing a few outputs to rightful inputs on the PLD and transferring it again, everything worked smoothly and as desired.
