WeDo 2.0 Keyboard Actuator - Laser Pointer Webcam Sensing

This simple robotic construction needs 2 computers: The first computer is needed as "a slideshow navigator pc", to show a document with slides (e.g. a Power Point document), either on a pc display monitor or on a wall, projected using a common video projector, but with the use of a Laser Pointer! The second computer does the navigation job, using this slim keyboard Actuator Construction (using WeDo 2.0), with the use of the Scratch (2.0 or 3.0) programming environment. This second computer uses a webcamera which feeds the video image of the Slide Show Navigator PC (either on a monitor or projected on a wall, as stated before) to the Scratch 'Stage' window as a background. By using the "Video Sensing" technique, the image of the Laser Beam is recognised when touching specific areas (i.e. Sprites) on specific locations and thus is activating the left or the right motor, which in turn touch the left or right arrow keyboard keys of the first computer ("the Slide Show Navigator PC"). So, just by using Laser Pointer movements, an individual can control the Slideshow, advancing or reversing the slides. On this video, a four slide show is being used. I hope you enjoy it!
