Instrument Stepper Motor
A Switec X27-168 stepper motor wired up to the Arduino. The pointer was moving when I took the photo, hence the blur. These little geared stepper motors are designed to be used in car instrument panels, as the speedo, rev-counter, fuel gauge and so on. Not a great deal of torque, but quick to respond and high resolution (due to the internal gearing).
There's a software library to drive this type of motor, called Gaugette: github.com/clearwater/gaugette
