Microstepping drive for a stepper motor is a well-known technique to improve the stepper motor performance. Normally, microstepping is carried at fixed pulse width planned. However, this method is ...

If the left sensor sees white, it turns right. If the right sensor sees white, it turns left. If both sensors see white (off track), it stops. The logic is handled by Arduino, and motor movement is ...

In order to improve the stability and reliability of the stepper motor under high speed and heavy load, a DC PWM drive chip is proposed to implement a high current drive stepper motor control system.
