As soon as the solder starts to flow, youre safer, because the solder distributes
heat automatically. Feed some more solder (not too much!) until you have a
nice, shiny solder joint. The whole process shouldnt take more than two to

joint a few seconds to cool down.
Repeat this for all six pin headers, and the result should look like this:
Test it by building the motion-sensing game controller, and play a video game
to relax.
Congratulations! You have just finished your first soldering job!
Learning How to Desolder
Lets face it: even if soldering isnt that difficult, things can still go wrong.
Sometimes you solder a part to the wrong place. In other cases you acciden-

mistakes, you have to remove the excessive solder.
The following figure shows two of the most popular tools for desoldering. On
the left you see a desoldering braid, and on the right you see a desoldering
pump (also known as a solder sucker).
