ICStation Team introduces to you this stepper motor control system based on the ICStation UNO compatible with Arduino. It uses a ULN2003 chip to drive it. 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 key 1, the stepper motor will rotate in the counter-clockwise direction.
Code for your reference:
Step 1: Components List
To change the rotating speed of the stepper motor by changing the input frequency of the pulse signal. And to cause the motor to rotate in the clockwise direction and counter-clockwise direction by controlling the transform sequence of the pulse signal.
