Using the 8BitDo Lite Yellow Bluetooth Gamepad is a breeze. To use it wirelessly, turn on your device's Bluetooth and pair the gamepad. You can choose to pair it as an X - input or D - input device according to your needs. If you prefer a wired connection, just plug the included USB Type - C cable into your device. When using it for robotics projects, make sure your project is Bluetooth - enabled. As for the battery, it can last up to 18 hours of use. When it runs low, charge it with the USB cable, and it'll be fully charged in one to two hours. Keep the gamepad clean by wiping it with a soft, dry cloth. Avoid exposing it to extreme temperatures or moisture. If you encounter any issues, you can check the official 8BitDo website for troubleshooting guides. And remember, if you want more advanced features, the 8BitDo SN30 Pro Gamepad might be a better fit for you.
