Step 22 Build Your Own Step 7 - Resistors

Last but not least, we add the resistors. This is about the most time-consuming task because there are several different values - be careful not to mistake one for another. Each resistor's value is encoded as three rings of different color, plus one ring for tolerance (gold = +/-5%). If you are not familiar with this color coding, have a look at the bill of materials, which shows the color sequence for each value. Alternatively, you can use a multimeter in resistance mode (Ohmmeter) to find out which resistor is which. Resistors are unpolarized, so it does not matter in which orientation you put them in.
