Be sure to heed all the safety precautions about soldering that we pro-
vide in Chapter 2. For example, don’t leave your soldering iron on if you
have to step away to let the pizza delivery guy in. And just in case a bit
of solder has an air pocket that could cause it to pop, wear your safety
glasses whenever you solder or clip leads and wires.- Connect and solder short lengths of 20 gauge red wire between the
remaining long LED leads. Then attach a 12" 20 gauge red wire to the
remaining long lead of the first LED pair, as shown in Figure 5-18.
These wires are the +V bus for the LED arrays; you attach the 12" wire to
a terminal block to supply voltage to the bus.- Clip the LED leads just above the solder joint.
Clip only the leads to which you have soldered the red wires; you need
the remaining leads in the next step.- Connect and solder a 12" 20 gauge black wire to the remaining short
LED lead on each pair of LEDs, as shown in Figure 5-19.
