Resistive flex sensor that increases resistance from ~10 kΩ (flat) to ~20 kΩ (fully bent); read with an analogue input and pull-up resistor. Strain-relieve the crimped pin end to prevent contact failure.
One of the two crimped terminals of the flex sensor. Adafruit describes the device as a resistor whose resistance changes with flexing, about 10 kΩ unflexed and about 20 kΩ fully flexed.
Other crimped terminal of the flex sensor. Use with a pull-up resistor to an analogue input or with a capacitor for RC timing per Adafruit guidance.
