• Không có điện:
  • Verify that the USB cable is securely connected to both the board and your computer.
  • If using external power, ensure the DC adapter is providing the correct voltage (7V-12V) and is properly connected.
  • Check for any visible damage to the power input jack or USB port.
• Lỗi lập trình:
  • Ensure "Arduino Uno" is selected as the board in the Arduino IDE.
  • Confirm that the correct serial port is selected in the Arduino IDE.
  • Check your code for syntax errors or logical issues.
  • Try a simple "Blink" sketch to verify basic functionality.
• Motor Driver Issues:
  • Ensure motors are correctly wired to the motor driver terminals.
  • Verify that the motor power supply is adequate and connected.
  • Check if the motor control pins in your code match the physical connections.
• Wireless Module Connection Problems:
  • Ensure the APC220 RF or DF-Bluetooth module is correctly seated in its socket.
  • Verify that the module is powered and configured according to its specific documentation.
