Chapter 1. PICDEM™ Mechatronics
The PICDEM™ Mechatronics is intended to be a learning tool for individuals interested
in Mechatronic design. Mechatronics refers to integrating electronic controls into
mechanical systems or replacing mechanical components with an electronic solution.
PICmicro® microcontrollers are ideal for use in Mechatronic systems due to their small
size, high efficiency, speed and abundance of peripheral configurations. Mechatronic
systems range in complexity from a simple electromechanical switch with output
multiplexing to the complex stabilizer control of a supersonic jet. The appliance and
automotive markets are notable markets in which mechatronic designs are becoming
more common place. The modern washing machine, for instance, once an entirely
mechanical design, incorporates microcontrollers to manage cycle times, read human
inputs and regulate the speed of the agitate and spin cycles.
This chapter introduces the PICDEM™ Mechatronics development board. It describes
the PCB layout, parts and electrical connection to the PICkit™ 2 Flash Programmer
and MPLAB ICD 2 In-Circuit Debugger. 1.2 HIGHLIGHTS

1.3 QUICK START GUIDE
The PICDEM Mechatronics Demo Board is programmed at the factory with a
demonstration program. The board must be configured as described in this chapter in
order to use the demonstration program. Once the board is configured and powered
up, the speed of the Brushed DC (BDC) motor on the board may be varied using the
potentiometer (POT1). The 8-bit hexadecimal interpretation of the position of POT1 is
displayed on the LCD. Board Setup
Using the provided wire jumpers, screwdriver and shunts (2-pin black hard plastic
jumpers), configure the board as shown in Figure 1-1.
1. Attach the leads of the brushed DC motor to Drive 1 and Drive 2 using the
2. Connect POT1 (on J4) to AN0 (on J13) using a wire jumper.
3. Connect P1 (on J1) to RD7 (on J10) using a wire jumper.
4. Connect N2 (on J2) to RD2 (on J10) using a wire jumper.
5. Connect the right and center pins on JP8 using a shunt. Board Power-Up
Supply power to the board in one of the following ways:
• Connect a 9-12 VDC (0.75 amp minimum) supply using J9 (see note below)
• Connect a 9-12 VDC (0.75 amp minimum) supply to the P21 and P20 screw
• Connect a 9 VDC battery to the battery connector.
• Connect a 5 VDC (1.2 amp minimum) supply to TP2 or TP3.
Note: The power supply part number is AC162039 (see buy.microchip.com). Packaged
with the MPLAB ICD 2, the part number is DV164007. Demonstration Program
Press CLR FAULT (SW5), which is near the bottom right corner of the board. Turn
POT1 clockwise to increase the speed of the motor. Note that the number displayed on
the LCD increases as you turn the potentiometer clockwise.
Try experimenting with the other sensors on the board:
• Move the jumper wire on POT1 (J4) to Light (J4). Vary the intensity of light shining
on the light sensor located near the top left corner of the board. No...
