Let’s begin!
1. Resistors: The values of resistors are given by a series of colored stripes. 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. “Figure 4:
Component Values and Locations” on page 11 is a good reference. 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.
The white graphics on the component side of the board give reference to the part number and
value. Figure 4 shows the component values and locations and may be easier to read than the
graphics on the PCB, so please use it to cross check your work.
Resistors are not polarized, meaning they can be installed into their holes in either direction.
It doesn’t matter which lead goes into which hole. The hole spacing of the resistors on the
circuit board allows the leads to be (gently) bent 90 degrees at the body of the resistor (1). This
allows the resistors to slip into their holes very easily. Resistors R13, R14, and R17 - R24 are
exceptions. Note how those two components are bent (2).
