typical controller system

• sensors
• acquisition system (Icube, PIC, Basic Stamp)
• mapping software (Max, PD, ?)
• output(?)

2
useful resources

• Fraden, a handbook of modern sensors
• MSI piezo manual
• acroname.com, infusion systems (!!!!)
• Datasheets!

3
other favorite resources

• Digi key
• American science and surplus
• smallparts.com
• Mcmaster-Carr / MSC industrial catalogs

4
what to sense?

• position, velocity, acceleration, rotation
• temperature, light, sound
• pressure, torque, bending
• ON/OFF
• ?

5
Switches

• discrete output
• toggle, normally on, off
• can provide visual and tactile feedback

6
Potentiometers

• common types linear taper, audio taper (log)
• rotary, linear, multiturn

Variable resistors
Variable resistor
R1
V output
R2
Vout Vref R2/(R1R2)
If sensor range is 10k-35k?, and R220k?then
Vout range is .66Vref .36Vref
