Tollbooth Project
The Tollbooth Project required me to engineer a circuit to control the motors of a tollbooth gate to open and close when pressed by a button.
A tollbooth is an example of a State Machine that utilizes input combo logic, memory flip flops, and output combo logic.
Criteria and Constraints:
4 inputs and 4 outputs
Gate must hit and activate both limit switches
Transition Table
The transition table uses binary code to illustrate the present and next state of the gate.
Once the open button is pushed, the gate opens until it hits the top limit switch to stop.
When stopped the gate is open.
When the close button is pushed, the gate closes until it hits the lower limit switch to stop.
When stopped the gate is closed.

These are the inputs/outputs of the design and what state they are in each step of the process.

The circuit I created was connected to a Vex tollbooth gate and successfully completed all tasks
