1.8.6
The temperature sensor and light sensor can be snapped off to give greater flexibility
in using these sensors. For example, the temperature sensor may be snapped off and
moved into a more hostile environment, while keeping the board within sight. Once,
snapped off, solder wires of the same length between the adjoining holes (i.e., JP3 and
JP4 for the temperature sensor) on the PICDEM Mechatronics Demo Board and the
sensor board.
1.8.7
If choosing to drive your own Brushed DC motor with the PICDEM Mechatronics Demo
Board at a voltage higher than +5 V
of 0-5 V
locations may be populated with resistors to create a simple voltage divider circuit. TP1
is the output of this voltage divider. See the schematic in Appendix A. “Hardware
Schematics” for further clarification.
1.8.8
The output stage of the board incorporates a simple current sensing circuit, which is
assessable at J15 (CURRENT SENSE). At this pin, the voltage is equal to current
± 10%. For instance, if a motor is being driven and it is drawing 0.9 amps, the voltage
at the header is 0.9 volts (± 10%).
