5. What’s Mechatronics?
The integrated design of products and processes that include mechanical and electrical components under intelligent control.  The underlying products are physical in nature (electromechanical, hydraulic, magnetic, etc).  There are sensors and actuators for interfacing with them.   There is "intelligence" through imbedded computing capability.  All these processes are highly integrated into sophisticated products and processes.

Let’s Make
Flashing Lights

20. Design Flashing Lights
Vdd P1 P0
 Digital I/O pins (0 or 5 volts)
 Current Limiting Resistors
 Light Emitting Diodes (LED)
 5 volt power

21. Circuit Model and Analysis
How big should resistors be?
Limit current to 10 mA
Assume:
no voltage drop across LED
P0 and P1
- go to ground
- have zero input impedance
Vdd P1 P0

22. Create Flashing Lights Hardware

23. Create Flashing Lights Software
'Program Demo Listing written by C. Radcliffe
'Define Variables and Constants '
left_led con 0 'left LED drive pin
right_led con 1 'right LED drive pin
blink con 100 'blink time (msec)
'Main Program
flash: 'Start of Program
high left_led 'turns left led off
low right_led 'turns right led on
pause blink 'wait for <blink> ms
low left_led ‘turns left led on
high right_led 'turns right led off
goto flash ‘repeat the blink
