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
