The motor used in the build is a Switec X27.168, the same motor used in the dashboard of tens of thousands of automobiles from dozens of different makes and models. 1 × Switec X27.168 Stepper motor / Analog gauge stepper breakout This is a tiny stepper motor used in in many automotive gauge applications. The motor draws so little current that it can be driven directly from the pins of most 5V capable PIC or AVR microcontrollers.
