Abstract: This paper describes the functions of PWM signal based on STC-51 single chip， introduces the theory of L298N to control DC motor. The software and hardware of the system are given and DC control motor programs developed by C language are discussed. Experiments explain that the system works stably and credibly， meets the demand of DC motor.

Key words: L298N, C language, DC motor, PWM
