I'm a complete beginner when it comes to working with electronics, but wanted to work through the $50 Robot tutorial so I would have something fairly simple to use as a learning tool, mostly for the programming side of things.
Now that I'm reading the photoresistor tutorial, I'm a bit unclear as to how to wire these things up. Specifically, the part where it says "You will also want to solder a blue (or whatever color) wire to the other wire coming out." is completely confusing. I'm not sure if this is supposed to be on the power or the ground/resistor side, or how this would work in either case.
Could someone please set this confused guy straight??
