7. Attach resistors between the pairs of LEDs, as shown in Figure 5-16.

Attach the resistors to the short lead on one LED of each pair (four pair

of each color) and to the long lead on the other LED of the pair.

8. Solder the resistors to the leads and clip the leads just above the
   solder joint.

Clip only the leads to which you have soldered resistors. Figure 5-16

shows how the LEDs and resistors should look at this point. Figure 5-17

shows a close up to help you see the soldering more clearly.
