stick to the standard Arduino Stepper library if full-step control is sufficient.In general though, I'd recommend alternatives: I've updated the X113647Stepper library to better reflect these issues.įeel free to borrow and use this library if it helps. add a half-step mode, where the standard Stepper library only provides full-step control.clarify the pin connections required to work with the 28BYJ-48.LEAP#432 ULN2003Module - deconstructing a ULN2003 module such as the X113647Īlthough the name is now a bit misleading, this project started as an attempt to address two issues:.
I've gone into more detail, including Fritzing parts, in the LittleArduinoProjects repository: the X113647 module is basically just the ULN2003A with additional LEDs and convenience pins for connecting power for the motor.28BYJ-48 stepper motor is a unipolar motor with 32 steps and a 64:1 gear reduction drive.The 28BYJ-48 stepper motor and ULN2003A-based X113647 Stepper Motor Driver Board is pretty common in Arduino kits, andĪvailable from various suppliers on aliexpress.
