51 single chip microcomputer automatic feeding machine design-L298N-vibration-key-LCD1602

The design is composed of STC89C52 single-chip circuit + L298N motor drive circuit + vibration sensor module circuit + button circuit + LCD1602 liquid crystal display circuit + power supply circuit.

1. Press button 1, motor 1 starts, and the LCD displays: Importing. When the vibration sensor detects the vibration, the motor 1 stops rotating, and at the same time, the LCD displays: End of feed.

2. Press button 2 to set the time for motor 2 to rotate, which is 5 seconds or 10 seconds. After pressing the button 3, the motor 2 starts and the LCD displays: Exporting. When the time is up, the motor stops rotating and the LCD displays: End of material.

3. The LCD displays the countdown time of motor 2 rotation.

4. After the system is powered on, the LCD display: Charger system.
