Motor control

Built the adafruit Motor shield, and now its time to control a motor.  I am using a Solarbotics GM2, and as Pololu says...This 224:1 gearmotor (gearbox with motor) is a great low-cost alternative to modified hobby servos or Tamiya gearboxes. The low-current motor is a perfect match for our qik 2s9v1 dual serial motor controller, and the compact size of 2.17" x 1.89" x 0.906" (55 x 48 x 23 mm) makes this unit an attractive choice for small robot designs.



At 5 V, the gearbox and motor provide 50 oz-in of torque and 38 RPM, which is slightly slower than a servo. The free-running current is 52 mA, and the stall current is 600 mA. A built-in safety clutch engages at approximately 60 oz-in.

This gearmotor comes pre-assembled, with the gears fully enclosed. There are built-in mounting holes, and the output shaft is 7mm in diameter with two sides flattened.
