Data & Observations
After all of that work, hopefully you're as eager as I am to test the system out and see how well (or poorly =P) it works. Below is a demonstration video of the project.
As you can see, the system works flawlessly! The distances we chose, 6cm through 22cm in 2 cm increments were all borders of the different speeds that the motor could be controlled at. The motor responded quickly and accurately, as did the LED bar letting us know what speed the motor was currently at.
