I'm in an Arduino programming class (it's mandatory + I'm not a programmer = bad combo) and am researching how to have multiple light sensors controlling a piezo speaker. No luck online, so I came here!
In the meantime, I'm testing the waters with LEDs, one per photocell. But in the end, I will like to have either (hopefully) one photocell per piezo speaker OR several (maybe 8 or more?) photocells for one piezo speaker.
My teacher recommended a MUX—this one in particular: https://www.sparkfun.com/products/9056 He has a lot of students to get to, and it's really hard for me to figure this out on my own.
Any help out there, please?

Thanks a million in advance!
