An interactive Arduino project that controls a DC motor via an L293D motor driver, a servo motor, and an Ultrasonic Sensor (HC-SR04). The system automatically stops the motor and changes the servo ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

A DC motor PID position-control system built on an STM32F100RB (Cortex-M3) running FreeRTOS. A companion Node.js web app (PC/) opens the STM32's serial port and exposes the commands as a REST API. The ...
