Hi.
Noob needs some help:(
Im trying to control a stepper whit the arudino lcd shield (6 button)
I whant the stepper to move "clockvise"when i hold "up" button down, and stop if i relese the button.
Same for "down" button but move "counterclockvise"
As im i noob at this im trying to read diffrent tutorials and copy codes in and out to make it work.
Now im stucked:(
Can someone look at this "code"
as you can see i realy dont know mutch about this.
Parts:
Arudino Lcd shield
Arudino Uno
Nema 17 stepper
Easy Motor
ps: i have try the stepper and it works but not in the way i whant whit another code i got online, so wire is good.
Thanks
