I would like to know, how can I move the stepper for a few steps by the left/right-Keys on the PC-Keyboard? (As long as I push the button). Stepper moved by ULN2003.
Is there any Idea?
Thank You

You need some app on the PC that is recognizing keystrokes, and sending data to the Arduino, via the serial port. That application is?
As long as I push the button
You want to send one value when the key becomes pressed, and another when the key becomes released. You do NOT want to send a continuous stream of characters.
What @Pauls has said about NOT sending a stream of characters is very important.
This Python - Arduino demo may give you a starting point for sending data to the Arduino. And you may be interested in Serial Input Basics
