Hardware Integration

Standard analog conditioning topologies for converting variable resistance into calibrated microcontroller inputs.

Connect F01 in series with a 10 kΩ pull-down resistor to an ADC pin. Simplest approach for touch detection and threshold triggering.

Place F01 in the feedback path of an inverting op-amp. Output voltage scales directly linear with force.
