Install the diodes

Diodes are polarized, having an anode and a cathode. When you insert the diode, match
the banded end of the diode to the banded end on the silk screen.

D9 Green LED
For the LED, you can identify the anode (triangle side) and cathode (line side) in the
following ways:
1. Anode is the longer of the two leads (assuming they are at factory length)
2. Cathode is the lead adjacent to the flattened side of the package. (very difficult to
see, so use method 1).
