What is the difference between a CDS cell, and a Phototransistor? Are they both light sensors? Or only one? Thanks. Zem.

Well, I was going to use one to jump the connection on a little circuit board that makes noise, so that I can wave my hand over it and it will play, will these work for that?

Okay, thanks! Which would be better used as a light sensor switch?
