signal
measurement
A/D converter
distance
ultrasound:
high frequence sound, undetectable for human ears
touching
pressure closes the circuit.

current flows only in closed circuit.
when flows: it's pressed,
when not: it's not pressed.
rotation
the engine is rotated by the current flowing in the circuit.

capacitive measurement:
The motor turns by the current flowing in the circuit (induction). The flow rate (force) can be measured.

OPTIcal measurement:

The teeth of the gear are detected by a distance sensor.
light
The LED (Light Emitting Diode)
emits light when powered,

and produces electricity
