5. What’s Mechatronics?
The integrated designof products and processes
that include mechanicaland 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 integratedinto
sophisticated products and processes.

12. Computers
•Typical Computers
–CPU
–Monitor
–Keyboard & Mouse
–High Speed Random Access Memory (RAM)
–Long Term Memory (HDD, Tape, CD, …)
–Other peripheral devices (modem, printers, …)

13. Microcontrollers
•All around us without human interfaces
–Cars (as many as 20-30 today)
–Toys
–Phones
–Appliances (your microwave and VCR)
•Small for control of machines
•For connection to machines not people
•Inexpensive ($2.00 -$5.00 or less)

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:
a)no voltage drop across LED
b)P0 and P1
-go to ground
-have zero input impedanceR=
