"This PCB driver is designed to control 4 DC motors and 2 stepper motors using the Arduino Mega 2560 as the main microcontroller. The driver is designed to operate the DC motors and stepper motors simultaneously and integrate with the Arduino Mega 2560 for control and monitoring. The driver uses electronic components such as relays, transistors, and resistors to regulate current and voltage on DC motors and stepper motors. The Arduino Mega 2560 is used to control the driver through a program developed using the Arduino programming language. This driver is designed to improve the efficiency and reliability of DC motor and stepper motor operation in various applications, including industrial, residential, and others."
