Playing the robot

You can test your robot with the project that you have created with the Blynk app:

1. Run the mini round robot project in the Blynk app by tapping on the Play button.

2. Move the joystick to forward, backward, left, and right by tapping and holding the center circle (Figure 2.34). When you release the center circle, it will automatically come back to the center and apply a break on the mini round robot:

3. While you move the joystick around, the x and y coordinates will display in the top right corner of the joystick widget.
4. You can fine tune the movements of the robot by changing the x and y coordinate value thresholds mentioned in your Arduino sketch.
