Option(s) for running/using a "5v Stepper Motor 28BYJ" for; "Fish Feeder Project" by mschiller. https://www.thingiverse.com/thing:1942222 or "Automatic Fish Feeder with micro servo control V2" by pcunha https://www.thingiverse.com/thing:736693 or "Automatic Fish Feeder" by coberdas https://www.thingiverse.com/thing:301532 or "..." Print the 5v Stepper "mounts" and "augers" in place of the servo "mounts" and "augers" for listed projects above. -OPTIONS- 1) Use DUAL steppers to drive V-Mixer & Auger. 2) Use DUAL steppers to drive V-Mixer & Auger driving spur mixer. 3) Use SINGLE stepper to drive Auger driving spur mixer. Advantage / Disadvantage -Steppers are more precise/accurate -Steppers are much quieter when operating than a 9g continuous servo -Steppers are much stronger than a 9g continuous servo -Steppers require extra drivers (+space) to project -Steppers are pretty easy to get your hands on "off the shelf" affordably whereas 9g continuous servos can be acquired "off the shelf" but your gonna pay for it. -Local hobby shops and places "like" MicroCenter are good places to start. -Cost comparison... 9g Continuous Servo = $6.37/unit (as of 3/15/18); https://www.ebay.com/itm/9g-Servo-360-Degrees-Continuous-Rotation-Variable-Speed-Bi-directional-FSEN/152902956753?hash=item2399b9f6d1:g:M3AAAOSwcv1adS5I 5v Stepper Motor 28BYJ (+driver board) = $5.70/unit (as of 3/15/18); https://www.ebay.com/itm/DC-5V-Stepper-Motor-ULN2003-Driver-Test-Module-Board-28BYJ-48-for-Arduino/252650061152?epid=2080013576&hash=item3ad31dfd60:g:QrsAAOSwA3dYNkB- NOTE: You will need to make appropriate changes to their "script(s)".
