3.31.3 Test Code

You can manually build blocks, or directly open the code file we provide: 3-31-Joystick Control Servo.ubp. If you have any questions about how to open code files or upload code, please back to 1.9 Upload Code.

Build code blocks:

1. In , drag and to the script area, and stack them together.

2. Determine whether the joystick is less than -90. If yes, the servo rotates to 180 degrees.

3. Determine whether the joystick is greater than 90. If yes, the servo rotates to 0 degrees.
