Introduction: 28BYJ-48 Stepper Motor Control System Based on Arduino With ULN2003 Chip
ICStation Team introduce you this stepper motor control system based on ICStation UNO compatible with Arduino. It uses ULN2003 chip to drive. The working voltage is DC5V. It is widely used on ATM machine, inkjet printer,cutting plotter, fax machine,spraying equipment, medical instruments and equipments, PC peripheral, and USB Mass Storage ,precise instrument,industrial control system,office automation,robot areas,etc.
2.When you press the key1, the stepper motor will rotate in the counter-clockwise direction.
Code for your reference:
Step 1: Components List
11.+5V DC power supply
Step 2: Schematic Diagram
To change the rotating speed of the stepper motor by changing the input frequency of pulse signal. And to realize the motor rotating in the clockeise direction and counter-clockwise direction by controlling the transform sequence of the pulse signal.
Step 3: Overall Hardware Connected Diagram
