The Two Panels That Make An Arrow
These are the two panels that make up an arrow.
On the top of the picture, you can see a white
wire that is soldered to the corner of the 9 1/2 inch
square piece of sheet metal attached to the lucite.
In this picture is the DOWN arrow, so the long wire
you see is the DOWN wire from the controller. To
the left of the long wire is a small wire, this is one
of the 4 GROUND wires that connects to the sheet
metal on peg boards.
