A stepper motor is an electro mechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The motor’s rotation has several direct relationships to these applied input pulses. The sequence of the applied pulses is directly related to the direction of motor shafts rotation. The speed of the motor shafts rotation is directly related to the frequency of the input pulses and the length of rotation is directly related to the number of input pulses applied. One of the most significant advantages of a stepper motor is its ability to be accurately controlled in an open loop system. Open loop control means no feedback information about the position is needed. This type of control eliminates the need for expensive sensing and feedback devices such as optical encoders. Your position is known simply by keeping track of the input step pulses.

The 28BYJ-48 is a small, 12 volt geared stepping motors. These stepping motors are apparently widely used to control things like automated blinds, A/C units and are mass produced. Due to the gear reduction ratio of approximately 64:1 it offers decent torque for its size at speeds of about 15 rotations per minute (RPM).

The motor can be used together with all stepper motor drivers for unipolar motors. The red wire should then be connected to ground (GND), orange/pink to M1 (or similar) and blue/yellow to M2 (or similar). Can also easily be driven by discrete transistors or a darlington driver (ULN2003).
