R2 required for v1.5 bare minimum #30

First of all thanks for this awesome shield! I just assembled my first v1.5 bare minimum board + temperature sensor. However, I was not able to turn the LEDs on on the first try. A look at the schematic revealed that R2 is actually required as it connects the level shifter output to the screw terminal. I soldered a 120Ohm resistor in that place (no 150 Ohms at hand) and it now works like a charm.

So I suggest updating the "Bare minimum" page to include R2.

New WiKi in the work as of right now. So your remark will be reflected there.
