Using the parts list above, populate the resistors by pushing them through the holes and bending the
leads outward at an angle to hold them in place. Resistors are not polarized, so they will work in any
direction. Turn the board upside-down to keep the components held in place while you solder.
You’ll use this same technique for most of the other components as well.
Don’t try to do all of the resistors at once. You’ll want to stop periodically flip the board and solder
everything, then cut the leads using the wire snippers to make room for more. Generally you don’t want
to do more than 15 to 20 resistors at a time or the bottom of the board will get too crowded.
If this is your first time soldering, watch tutorial videos on YouTube and make sure you get it down
before you begin. You don’t want to practice or experiment on this board!
