Soldering an LED (pg2)
Next, slide the coiled resistor up the LED leg a bit and apply the solder by
touching the iron and the tip of the solder coil to the wrapped resistor. For most LED’s,
you should keep your soldering iron from 335˚C to 400˚C. Leave just enough solder to
secure the two wire leads together. Then trim the excess wire from the LED leg and the
resistor leg, making sure not to cut into the solder itself and separate the two again.
Next, repeat the same process with the wire by coiling about a cm of exposed
(stripped) wire around the other end of the resistor and adding solder the same way.
Then repeat this step for the negative wire and LED leg. (NOTE: you only need a resistor
on one LED leg) Again, trim off any excess LED leg metal.
Finally, twist your attached wires tightly for a tidy finish, strip off a little shielding
at the end of the wire, and you should be done! Test your LED by connecting the
negative wire to negative on your power source and positive to the positive. (in this
case, 9V-12V) If you see light, you’ve got it right!
