Computer Science Internet of Things (IoT) Arduino motor control is the practice of using a programmable Arduino microcontroller to precisely manage the operation—including speed, direction, and position—of various electric motors like DC, servo, and stepper motors. This is accomplished by writing code that sends control signals, often using Pulse Width Modulation (PWM), from the Arduino's digital output pins to a dedicated motor driver circuit, which is necessary to handle the higher power requirements of the motor itself. As a core component of robotics, automation, and physical computing, it represents a practical application of computer science principles to create interactive systems and is a foundational element for many Internet of Things (IoT) devices that need to manipulate their physical environment.
