Working Pld design
The tollbooth gate state machine has four inputs and four outputs. The four inputs are open switch, close switch, open limit, and closed limit. The two state variables are Qa and Qb. The four outputs are motor open, motor closed, gate open, and gate closed (GC).

conclusion
Overall I have learned a lot from this project. For starters, I learned to take advantage of my strengths and my partners strengths to get this project completed with a lot less help than i was given in the previous projects. However, we made many mistakes along the way. I chose to ignore the diagrams given and initially wired based on my prior knowledge. We used two limit switches as well as a motor that is activated when switch is pressed. This project was similar to the previous projects completed in that a programmable logic device was used as well as LEDs, flip flops and combinational logic. This project was different from previous projects in that limit switches were utilized here as opposed to light sensors. I didn't learn much about reading schematics during this project. I was not aware of all of the diagrams in the back of the packet so I went about wiring the breadboard and chip on my own. However, reading and interpreting schematics has become easier and faster compared to the beginning of the year. Next time, I would make sure to read through the entire packet and try to be more involved in the assembly of the mechanism itself.
