The document outlines the ME456 Mechatronics course led by Professor Clark J. Radcliffe at Michigan State University, detailing office hours, contact information, and course scheduling. It highlights key aspects of mechatronics, including the integration of mechanical and electronic systems with computer controls, as well as practical projects focusing on microcontrollers. The grading system and initial assignments, including hands-on lab work and design projects, are also described.

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.

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:
a) no voltage drop across LED
b) P0 and P1
- go to ground
- have zero input impedance
R = V
I = 5v
