Features:

• Four LEDs to indicate the active coil
• Simple interface with microcontrollers like Arduino
• Can handle up to 500mA per channel
• Wiring and Control

Specifications:

• 5V Stepper Motor (e.g., 28BYJ-48)
• Voltage: 5V DC
• Type: Unipolar stepper motor
• Steps per Revolution: 32 steps (11.25° per step)
• Gear Reduction Ratio: 64:1, resulting in 2048 steps per revolution
• Torque: Approximately 34.3 mN.m
• Speed: Around 15 RPM
• ULN2003 Driver Board
• Purpose: Controls the stepper motor by energizing the coils in the correct sequence.

Basic wiring setup:

• Connect the motor to the ULN2003 driver board.
• Connect the ULN2003 to the Arduino: IN1 to Arduino pin 8/ IN2 to Arduino pin 9/ IN3 to Arduino pin 10/ IN4 to Arduino pin 11
• Power the motor with an external 5V power supply to avoid damaging the Arduino.
