                                          Creating the Main Controller
                                          Printed Circuit Board
                                          To fabricate the controller printed circuit board (PCB), photocopy
                                          the artwork in Figure 6.36 onto a transparency. Make sure that
                                          the photocopy is the exact size of the original. For convenience,
                                          you can download the file from the author’s Web site, located at
                                          www.thinkbotics.com, and simply print the file onto a transparen-
                                          cy using a laser or ink-jet printer with a minimum resolution of
                                          600 dpi. After the artwork has been successfully transferred to a
                                          transparency, use the techniques outlined in Chapter 2 to create a
                                          board. A 4-inch   6-inch presensitized positive copper board is
                                          ideal. When you place the transparency on the copper board, it
                                          should be oriented exactly the same as in Figure 6.36. It would be
                                          a good idea to create the circuit board for the remote control at the
                                          same time.
