Constraints
My partner and I had to design a circuit from the ground up that would successfully detect a "copy jam". A copy jam is whenever two of the neighboring photo transistors is covered. We had to design this circuit using combination logic and flip flops.

circuits
resistors allow the power to go back to default when there is no input.
The combination logic allows the photo transistors to be next to each other.
Flip flops are used to detect when both photo transistors are on and also to make sure the buzzer stays on until it is cleared.
The led goes off because it is set up to only go off while breaking two beams while the buzzer needs to be cleared for it to stop.
Conclusion
This project uses combination logic and flip flops, unlike previous projects. This project also uses actual photo resistors and other components so it could actually work in real life.
