1
typical controller system sensors acquisition system (Doepfer box,) mapping software (Max) Output (Reason)
2
useful resources Fraden, A Handbook of Modern Sensors MSI piezo manual sensorwiki.org Datasheets for components
3
Parts sources Digi-Key catalog Sparkfun.com Mouser catalog Mcmaster-Carr catalog Acroname Robotics
4
what to sense? position, velocity, acceleration, rotation temperature, light, sound pressure, torque, bending ON/OFF, constant or toggle
5
Switches discrete output Toggle,normally on, OR normally off can provide visual and tactile feedback
6
Potentiometers common types: linear taper, audio taper (log) rotary, linear, multiturn +V ref GND V out
7
Other variable resistors: V output Variable resistor R2 R1 Vout = Vref R2/(R1+R2) If sensor range is 10k-35kΩ, and R2=20kΩthen Vout range is.66Vref =>.36Vref
8
Bend Sensor resistance increases when bent
9
FSR (Force-Sensing Resistor) resistance drops when pressed
10
accelerometers inclination, acceleration
11
Typical data sheet for accelerometer
12
Specs & pricing table for accelerometers
13
IR distance sensors Sharp GP2D12 (AKA the toilet sensor)
