 Thread a Nylon washer and then a ½″ round spacer on each of the 7/8″ screws.
 Attach the screws through the holes in your board and into the standoffs below,
but do not tighten them all the way yet.
 Slip the hooked ends of the whisker wires around the screws, one above a washer
and the other below a washer, positioning them so they cross over each other
without touching.
 Tighten the screws into the standoffs.
 Use the 220 Ω resistors (red-red-brown) to connect digital pins 5 and 7 to their
corresponding 3-pin headers.
 Use the 10 kΩ resistors (brown-black-orange) to connect 5 V to each 3-pin
header.
 Make sure to adjust each whisker so that it is close to, but not touching, the 3-pin
header on the breadboard. A distance of about 1/8″ (3 mm) is about right.
