Copy Jam
In this project, my partner (Cade) and I worked as a team to design and create a circuit that had a purpose to inform the user of a paper jam (comparable to a real life situation of paper getting jammed up in a copier). This would occur when the LED's next to one another were covered up, and the sound of an alarm and the light would go off.

Circuits
Resistors limit the amount of power going through the circuit, but we did not use them since we did not have to construct the design. The combinational logic circuit is there to ensure the motor stops running, the LED comes on and the buzzer goes off when there is a jam. It allows the LED to turn off and the motor to resume as soon as the jam is fixed while the buzzer will not turn off until the reset button is pushed. The reset button controls the buzzer using a flip flop with the reset button connected to the clear and the buzzer connected to Q out. Since the buzzer is just used to alert the user there is a jam, it can be reset while the jam is still present. This is more efficient for the user of the copier. The resuming of the motor and the termination of the LEDs light will indicate the jam has been clear because they are directly connected to the three inputs from the sensors. We only had to create this design in PLD mode in MultiSim.
Conclusion
This project was different than other projects we have done so far. It combined many of the skills we have learned in this class all into one project. Unfortunately, the class was having trouble getting the construction of the project to work correctly so we only had to build the circuit in PLD mode of MultiSim. This made the project simpler, but I was still able to learn new things from starting the construction and finishing the part we needed to for the project. I learned new things with the flip-flops and how to build the construction before we were told we did not have to. I also learned how to know which gates to use. In the end, we turned out successful with out creation on the computer.
