Picture 6Decepticon says

#1) Where are the beats? All I hear is an Atari tone generator.
#2) So you put photo-resistor in a bag of chips (or not necessarily in
a bag of chips considering someone was doing it with a
sandwich)…maybe a better explanation is in order.
#3) Your title is way misleading.

I think It's actually a very constractive comment, thank youDecepticon, you defiently right I need to post a better explanation.
