Schrittmotor am Arduino

Anschluss des Schrittmotors an den Arduino

zum Anschluss des Schrittmotor an ein Arduino Board werden ein Schrittmotor Treiber und zwei I/O Pins benötigt.

Programm für den Arduino

Das Arduino Demo Programm kommt ohne zusätzliche Library aus und steuert den Schrittmotor für jeweils 200 bis 1000 Schritte mit jeweiligem Richtungswechsel an. Am Arduino Nano CNC Shield wird der Schrittmotor der X-Achse angesteuert.
