Look at this video:
http://youtu.be/LgHvbeBRNbk?list=UU3gzJ5q340VA1yf9Icxp4EAI have this voltage regulator card.. works just fine.. with an input and output and a potentiometer in between..
but the there is a display added and 2 buttons.. when I hold the right button as you see in the clip I can change.. ehh.. something.. but I don't get what it is.. and it doesn't seem to acctually change anything in the output..
what is it I am missing here..

(In summary, left button = on/off, right button = input/output voltage display, long press right button = calibration mode (left/right is up/dn then), long press again to exit calibration mode).
Thank you.. I will try this later
