Let's begin!
4. Resistors: The values of resistors are given by a series of colored stripes on their body. There are
several tutorials online describing how to decode these stripes, but we will identify each resistor
for you by simply naming the stripe colors, and giving you the value and the part number.
Fortunately, there are only two resistors in this mod kit, so it shouldn't be too difficult to tell them
apart. "Figure 3: Component Values and Locations" is a good reference for all the components.
If you are color blind or can't see the stripes clearly, then you must use your digital multimeter
to measure the resistance of each resistor. Resistors are not polarized, meaning they can be
installed in their holes in either direction. It doesn't matter which lead goes in what hole. The two
resistors in this circuit are installed standing upright on the PCB so bend one lead nearly parallel
with their bodies and install them standing up (1,2).

a. Start with the 220 ohm resistor (R1). This resistor is labeled RED, RED, BLACK, BLACK,
BROWN. Bend the lead as described above and install it on the circuit board as in the picture
(2). Bend the leads out on the back to keep the resistor from falling out of the board (3).

b. Next do the 1K resistor (R2), labeled BROWN, BLACK, BLACK, BROWN, BROWN.
Compare to its picture in the BOM. Find it's location on the circuit board; install and bend the
leads the same as the previous resistor (4).
