|Figure 1: This is a basic schematic of my circuit. It excludes things such as power to components and some ground.|
2. Explain your setup.
Power will come to my setup in the form of a 5V pulse of electricity. This 5V will be directly connected to my motor. This motor will pull the stopping block in front of my ball, which will allow it to fall down the setup. The ball will land on a switch and activate it. This will allow 5V to run through the op-amp, increase to 7V, and trigger the relay. The relay will send voltage to an LED to start the next circuit while also powering a 555 timer that's 1st and 4th output will be hooked up to an AND gate. When this triggers, the LED will have power.
3. Provide photos of the circuit and setup.

4. Provide at least 2 new videos of your setup in action, one being a failed attempt.

One of the main failures that I faced was getting the mechanical component to successfully land inside of the catching mechanism that I had built. I tried to overcome this by taping the component onto the table to prevent the small movements between attempts. At first I had trouble getting the relay to trigger when I wanted it to, but I solved this by playing with the resistor values on my op amp until I could get it to work. I also have trouble will getting the ball to start rolling. It is not perfectly round so sometimes when the stop block is released, the ball remains there.
