I bought a DC 5V 28YBJ-48 Stepper Motor for Arduino ((Works with Official Arduino Boards /2 PCS) (from here: http://dx.com/p/dc-5v-28ybj-48-stepper-motor-for-arduino-2-pcs-148819)
Here are the specs: Diameter: 28mm; Voltage: 5V; Step Angle: 5.625 x 1/64; Reduction Ratio: 1/64; Can use uln2003 chip as driver
Now, i'm totally new at this, and from the test examples i could find this thing is really slow. Is that what the 1/64 stands for?
And if that's true, than what's a good motor to drive a robot?
