The Arduino Opta micro programmable logic controller (PLC) provides a unique entry point into the automation field. Automation fields like smart homes, process controls, and robotics are project areas ...

This project controls the speed and direction of a DC motor using an Arduino, a potentiometer, and two push buttons. It requires an L293D motor driver IC to function. Functionality ⚙ This program ...

// SPEED=1..20 maps to PWM duty via a geometric curve from MIN_DUTY (s=1) to 255 (s=20). // SPEED=0 stops the motor. Stopped -> running triggers a 10s full-duty cold start. const int MIN_DUTY = 42; // ...

ROS2 Motor Control Most robotics students stop once the Arduino code is written. But a professional robot requires a robust communication layer to bridge the gap between hardware and high-level logic.
