ELEGOO 5 Sets 28BYJ-48 ULN2003 5V Stepper Motor with ULN2003 Driver Board

BUILD FIVE LOW-SPEED MOTION PROJECTS: Create clocks, gauges, rotating displays, feeder gates, vents and small robot mechanisms; five matched motor-and-driver sets support classroom builds, maker prototypes and spare replacements, 5 V UNIPOLAR GEARED STEPPER MOTORS: Each 28BYJ-48 uses a 5-wire, 4-phase design with nominal 1:64 reduction for controlled low-speed movement in light-load positioning projects, ULN2003 DRIVER BOARDS SIMPLIFY CONTROL: Connect control signals to IN1-IN4, power the motor through the driver board and use four onboard LEDs to view the active coil sequence during setup and testing, SET UP FOR SMOOTHER ROTATION: Use a regulated 5 V supply with sufficient current, connect controller and motor-supply grounds together, verify the motor plug and IN1-IN4 sequence, and reduce speed if the shaft buzzes or vibrates, FIVE COMPLETE MOTOR-DRIVER SETS: Includes 5 28BYJ-48 stepper motors, 5 ULN2003 driver boards and 10 female-to-male jumper wires for multiple prototypes and replacement builds.
