Figure 5.8
Driver boards and
interface wired up for
testing.

1 am using an old PC power supply for each of the driver boards
and taking 12 volts for the motors and 5 volts for the circuit. To
power the inte rface board. take 5 volts from one of the boa rds at
the positive side of a capacitor co nnected to 5 volts and gro und
(see Figure 5.9).
Attac h the interface ground to the co mmo n ground of the driver
boards.
