Circular Soft Potentiometer (Ribbon Sensor)

Manufactured by Spectra Symbol, these are nice little ribbon controllers (also known as 'soft potentiometers') with an adhesive backing.

Outer lead A
One outer lead of the nominal 10K soft potentiometer. Adafruit says one side pin is connected to ground through a 10K series resistor for use.
Type · passiveVoltage · Use through 10K series resistor; do not connect directly to ground/power per Adafruit product page.
Wiper / middle pin
Middle pin resistance changes relative to either outer lead depending on press position; read as the analogue output. Adafruit says it floats with no pressure.
Type · analogVoltage · Analogue voltage ranges from about 1/3 Vcc to 2/3 Vcc in Adafruit suggested circuit.
Outer lead B
Other outer lead of the nominal 10K soft potentiometer. Adafruit says the other side pin is connected to Vcc through a 10K series resistor for use.
Type · powerVoltage · Vcc may be 3V, 5V etc through 10K series resistor per Adafruit product page.
