It's not a real marble run... or is it? Here is your marble... I don't want it, so take it back...No, it is your marble, here it is...
this discussion continues untill you switch off the unit. In the box you can install two 28BYJ (increadibly cheap) steppermotors or the slightly smaller version 24BYJ. Power supply: Three AA batteries. Make sure both arms are in line, otherwise the marble does not follow the track.
This Arduinmo sketch makes it run:
