For my musical instrument assignment, I re-read and did what I saw from the Week 4 code on the website. The code is almost similar to what was done on Tuesday, but I changed from 1023 to 2000 under from low 0. If you turn the knob one direction, the speaker's sound system makes a deep and long lasting pitch. Turning it the opposite direction will result in making the sound higher and/or play rapid beats.
