| Abstract: | A DC motor control and speed detection system is designed using T measurement with STC89C52 as a single-chip controller, L298N chip as a motor control chip and a S177 Hall element sensor. The system can real-time control the motor speed and direction, and simultaneously display the motor speed and steering. This system has features of sensitive control, accurate speed detection and the simple circuit structure. |
