Step 1: Install four resistors
Step 2: Install the diode
Resistors have a low profile, sitting closer to the board than taller compo-
nents, so it’s a good idea to install them first. Their locations are marked with
numbers on the board.
Resistors are not polarized, so it doesn’t matter which lead goes in which
eyelet. They can be installed in either direction.
Diodes are polarized, so they need to be installed in the correct orientation.
Note the stripe around one end: this marks the negative (minus) lead of the
diode. On the circuit board, the printed outline of the diodes also shows this
stripe. Install each diode so that its stripe matches the direction shown on
the circuit board.
Solder D1 in its marked location now.
The leads on diodes sometimes vary in diameter. If the leads don’t fit into
the eyelets in the circuit board, trim them at a steep angle to create sharp
points that fit into the holes.
