Summary

This circuit is designed to control a 28BYJ-48 Stepper Motor using an Arduino UNO microcontroller and an SBT0811 driver. The Arduino UNO interfaces with the SBT0811 driver by sending control signals to the driver's input pins. The driver then outputs the necessary signals to the stepper motor, causing it to rotate. The specific wiring and control logic are detailed in the following sections.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
