Demo Video


Using Arduino, Processing, Webcam, and Wiimote

When the capture button is pressed, Arduino serial is detected by Processing and the webcam frame is saved. Using Johnny Lee's Wiimote Whiteboard software, infrared LED position is detected by Wiimote and converts to mouse XY position. In another Processing window, the saved frame is loaded under a white canvas.
