Disc Potentiometer

A 10 kΩ thumbwheel potentiometer wired as a voltage divider: turn the wheel and SIGNAL runs from 0 V to VCC, read by one analog pin. The wheel lies flat and overhangs the board's edge, so a thumb turns it from the side.

Track: 10kΩ thumbwheel
Wheel: 16mm across
VCC: 3.3or 5 V, the top of the range
Wires: 3GND, VCC, SIGNAL

Turn it over and see the three holes to wire: GND, VCC and SIGNAL, the wiper. VCC is the top of the range, so match it to your board.
