If you have never used an Arduino before, the video below will help you. It shows you how to install the Arduino IDE on your computer and copy a sketch to the Arduino. The downloaded .ino file (previous step (20)) is such a sketch and you can use it according to the instructions in the video.

During the development we have been able to gain some experience in using it. So that you can benefit from it, below is a list of recommendations:

• After starting the Arduino, a calibration of the sensors starts. For this, you need to begin with looking straight. In the following step, the Arduino tells you the direction, in which you have to look. After looking in each direction, the calibration is finished.
• The Arduino understands two eye movements. The first one brings you to one of the four areas and the second one navigates you in between them, as visualized in the customization tool.
• If you close the eyes for 3 seconds, you switch back to the main menu. This duration can be customized in the settings of the customization tool.
• Try not look to much in the surrounding area, because it can trigger eye movements
• Try not to move the glasses too much

If you have any further experience, please write a comment and we can include it here for other users. :)

Have fun using it - we look forward to your feedback!
