Raspberry Pi Stepper Motor Control with L293D / ULN2003A

Stepper motors are ideal for applications where it is necessary to know the angle of rotation, for example in robotics. Unlike a normal motor, stepper motors can control the steps individually and can therefore detect the exact position.
For easy controlling such a motor, a driver IC like the L293D or the ULN2003 are needed. The use of both drivers is shown in this tutorial.
