51 motor control system design-L298N-key-potentiometer

This design is composed of STC89C52 single-chip circuit + L298N motor drive circuit + button circuit + potentiometer speed control circuit + power supply circuit.

1. The speed of motor 1 can be adjusted in real time through the potentiometer.

2. The forward and reverse rotation of motor 2 can be controlled by pressing the button. That is, when the button 1 is pressed, the motor 2 rotates forward. Press again, motor 2 reverses. Press again, motor 2 stops.

3. Press button 2 to set the forward speed of motor 3: press button 2 once, motor 3 rotates at low speed, press it again, motor 3 rotates at medium speed, press it again, motor 3 rotates at high speed. (The specific speed is determined by Tongwang Technology)
