Step-by-step instructions
Solder
all
the
resistors
first.
Polarity doesn’t matter for them,
so
you
can
orient
them
in
whichever way you choose.
In case you haven’t noticed: You
do NOT have to read ring codes or
use a multimeter to determine the
resistor values. Each bag contains
unique sets of resistors, so you
will not find e.g. two sets of 4
resistors
in
the
same
bag.
The
information on the bag labels is
enough
to
be
able
to
tell
the
resistor value.
Some of the resistors in your kit
may
be
white,
green
or
blue
instead of beige as shown here.
Don’t worry, they all work pretty
much the same.
