Helicopter Game (Sensor Display)
For my sensor display I wanted to make use of the proximity sensor. I chose to create a portrayal of an old flash game I remembered playing. I’m not sure what the origin of it is, but a portrayal of it can be found at http://www.helicopter-game.org/ . However, for my version the helicopter is controlled by the height of the player’s hand over the sensor device. The device is meant to look like a black box which is typically associated with aviation. I made sure to use similar colors for the game and the box.
Here is a video of the project running:
