Motor speed controller system using microcontroller: article / Mohd Shahril Mohd Sakri

This project is to design the dc motor speed controller using a microcontroller. A sensor will be used as distance measuring element. The design system will automatically operate as sensor detecting certain distance the car is speeding. As a controlling center of the system, microcontroller will be used. The ultrasonic sensor is an option to the measurement of the distance between the vehicle and retrain object (another vehicle). In this project, dc motor is used to represent the speed of vehicles that is liable to change followed by the distance that is affected by the sensor.
