Conductive touch buttons for fischertechnik

Buttons printed with conductive filament for fischertechnik to be used with capacitive touch hard- or software.

Can be used with:

• Dedicated touch pins of some specific microcontrollers, e.g. ESP32 touch sensor pins
• I2C touch sensor IC/module, e.g. MPR121 module from Adafruit or noname China module
• single contact touch sensor IC/module, e.g. TP223 (see my note on using the red modules with external contacts here)
• Software polling, e.g. CapacitiveSensor Library (additional resistor needed) or ADCTouch Library (no additional resistor needed, only for AVRs)

See also this design for the red TP223 modules.
