Cornholio Schematic Questions

[row]

Hello all, I'm trying my hand at this for the first time with a bit of a background in circuits and such. I've been working on piecing together the Cornholio and I have a few questions about the schematic.
1. What does the circle with "pin" in it mean?
2. What does VC mean? I have been searching and just found that it indicates a voltage, is it just the +9 volts?
Thank you for any help!

Pin is the actual solder pad for the input and outputs. VC is +9v VB is usually +5v, or there about, usually. In the power section, you will see a voltage divider, which is typically two resistors with the VB flag between the two. This schematic doesn't feature this particular feature.Hope this helps.
