Sprint One Review
The goals for sprint one was to test an initial device to select which ball color to drop. We designed a mechanism able to select the balls by color. In doing this we learned the difficulties of properly handling the balls, and also set a foundation for how future mechanisms could work.
We also designed a rack and pinion to move the tubes, which allowed us to test code for dropping the balls. We reached a very basic MVP where if we manually loaded the balls we could spell PIE with the device.

Sprint Three Review
Our goal for sprint three was to have all the subsystems working independently. This was mostly achieved. The ball sorter and dropper mechanism was fully functional and in its final state. The final frame was also fully assembled. Test versions of the elevator were also working.
At this point in the project our biggest challenge came from the carousel not moving smoothly. It took over four iterations of our sprocket, as well as multiple adjustments to reduce friction, before the carousel moved smoothly under power from the stepper. At this point in the project, the pieces were in place to finish the project, they just had to be assembled into a functional system.
