I see how the Breakout Board connects to the Twine with the white cable. I also see GND, In, and 3.3V. So, a few questions:
1. I'm assuming the BB requires 3.3V in... not a problem there.
2. Understand GND... not a problem there.
3. What does the In pin require? Is it simply looking for HI/LOW or digital 1/0 or what?
