3 Touch Sensors

Capacitive sensors may be implemented to simply detect contact as a button replacement, or functionally extended to provide a relative measurement of distance (proximity), 1D position (slider or wheel) or 2D position (Touch Surface)

In each case, the modular library detects a touch contact by a change in capacitance exceeding a pre-configured threshold. Once a contact has been confirmed, the various post-processing modules use the calculated touch delta to interpolate amongst neighboring sensors and calculate the location of the touch position or relative proximity.
