  1. Hi! I like your vidoes and how to interfacing opencockpits! But I'm a little confused about whats common and what is switching the outputs with this kind of setup from opencockpits. Is it common GND or commons anode? Is it gound that are switching the LED or is it the +5V?

  2. Hello, Could you please tell me what is the capacitor on the master card? How many farads is it? I do not have it on my previous generation master card. Thank you.
