module, with the ribbon cable attached and ready
to be connected to the stripboard.

Step 6. Prepare the Stripboard
Figure 4-11 shows the stripboard layout for the
project. Note that it is shown as viewed from
above.
Begin by cutting the stripboard to size: we need
15 strips, each with 20 holes. A strong pair of
scissors can do this just fine. Using a drill bit, and
twisting it between your fingers, cut the track in
the locations marked with an “X.” Figure 4-12
shows the back of the board, ready for soldering.
