2. Explain your setup.
-The circuit begins with a 5V source connected to one end of a photocell and a ground source connected to the other pin of the photocell. The photocell is then connected to pin 3 of the Opamp. A ground source connected through a 3kOhm resistor is then connected to pin 2, this same source is also connected to pin 1 through a 3.9kOhm resistor. A voltage source of 5V is connected to pin 4 of the Opamp. Pin 1 of the Opamp which is the output is connected to pin 2 of the relay. A voltage source is connected to pin 1 of the relay and a ground source to pin 5. The DC motor is connected to pin 3 and and 7 segment display is connected to pin 4. The circuit begins with the 7 segment display turned on, since all the voltage going through the relay is coming out at pin 4. When a light source is applied to the photo sensor, it should switch the relay from pin 3 to pin 4 and make the DC motor go off, therefore starting the Rube Goldberg.

Successful Attempt5. What failures did you have? How did you overcome them?
-There were several problems I experienced while setting up my Rube Goldberg project. One of the biggest ones was making my circuit complicated enough. Although I did manage to implement all 5 necessary components into a small and not so complicated circuit, it was still too simple. I will fix it this upcoming week by modifying the input and output of my circuit coming from and going into the other Rube Goldberg projects. I will add more components in order to achieve a more complex circuit. One of the other failures was being able to come up with a mechanical part that could easily be adaptable to the following circuit, since it has to go from one side of the table to the other. I eliminated 4 different concepts before finally finding the perfect one.
