In the Unity project, open the Hub-edit scene & press the Play button. 

Put the NextMind headset on and press the power button. In the Unity player pane, click on Calibration, connect to the NextMind, and complete the entire calibration process. 

When calibration is complete, return to the main menu and click Discovery.

You should see the three CubeTag objects you created and edited earlier.

Choose a CubeTag object and focus on it, triggering the green triangle to form at its center.

At this point, the Unity scripts should send a serial message to the Feather indicating which cube was focussed, in turn causing the servo pointer to rotate, indicating that same cube you chose.
