State Graph

The state graph shows how the equations of the circuit will show outputs in each state. The four states are listed as S0, S1, S2, and S3. The inputs are either 1's or The outputs are the controls on the motors (motor open and close, gate open and close). This graph represents the physical process:
-When the top limit switch is pressed, the motor will know to turn off
-When button one is pressed, the motor begins moving in the opposite direction (down)
-When the lever hits and presses the lower limit switch, the motor turns off
-When the button is pressed again the lever will move up again and this cycle continues
-When the top limit switch is pressed, the motor will know to turn off
-When button one is pressed, the motor begins moving in the opposite direction (down)
-When the lever hits and presses the lower limit switch, the motor turns off
-When the button is pressed again the lever will move up again and this cycle continues

Conclusion
Dear Ms.Zienty,
This project was actually one of the more fun projects to work on. I enjoy doing the state graphs and transition tables (they're kind of like puzzles). The Boolean wasn't difficult and the VEX tower wasn't difficult to build. The biggest challenge was getting the breadboard to work with the PLD circuit. The wiring on the breadboard got a little bit confusing with the IC chip but eventually we figured out where we were making mistakes.
One of the biggest challenges with this project was understanding how to adjust all of the different variables to work correctly. However, this became easier when instead of just thinking about the variables as just letters and numbers and actually thinking about how they react to each other by what they actually represent.
I think that this was a good project to end on as it connected a lot of different skills that we learned over the course of this class. DE has taught me a lot about critical thinking and to not give up when it seems like there is not solution to a problem. Thank you for everything you taught me and all of your help over this year. I ca't believe that I've only got one class left.
Sincerely,
Lindsay
