+ | ==== 28BYJ48 Stepper-Motor ==== | ||
+ | Mit ULN2003 Driver Board. Auf pins 16, 17, 5, 27 und Limit-Switch mit externem Pulldown auf Pin 34. | ||
+ | |||
+ | Erste Tests sind vielversprechend. Das Ding läuft leise und erstaunlich präzise. Hat ein bisschen Spiel, verliert aber keine Schritte und kann den Limit-Switch wieder genau anfahren. | ||
