7. Display Board:
a. Seven segment display: Carefully install the seven segment display onto the display board. It
is critical to note which direction the display is orientated compared to the dot on the top
right of the board: the decimal places should be at the bottom of the display and the dot on
the top right of the board (35,36). Do not install the display upside down! Solder and clip
the leads (37,38).

b. Display board headers: Break the long (21mm) headers into two sets of 6 pieces. Install
these headers on the display board as in the photos (40). Use the same technique you used
installing the previous, shorter headers...hold one of the pins to the board while tacking the
pin to the board with solder (40). Then solder the rest of the pins. Before you solder them,
make sure that these headers are perpendicular to the surface of the board (not at an angle).
