How to DIY a mini balance car on your own? This balance car kit is based on Arduino development platform. We mainly use REV4 as core and balance shield with built-in MPU-6050 as drive board to test the car body posture.
The balance shield comes with a Bluetooth interface, fully compatible with the Bluetooth XBee module (only compatible with Android system).
When connecting to Bluetooth, you can easily control the moving direction of balance car with Bluetooth APP, making a variety of unique postures.
To facilitate the operation control, Bluetooth APP has both key and gravity control modes. 
Moreover, it adds the function of adjusting the balance angle and PID parameters as well, so you can perfectly adjust and control the balance car.
No need to worry how to play it. We can provide you with all assembly components, as well as the corresponding installation, debugging method and program
