Little by little we’re moving to https://www.ourtechart.com/augmented-reality/augmented-reality-using-arduino-sensors/
In this Augmented Reality tutorial the 3D cube’s color and transparency are changed using 4 optical sensor (TCRT5000) information.
Download # Arduino Code (*.ino file)
Download # Processing Code (*.pde file)
Download # Hiro Marker (*.pdf file)
(Processing software itself is available to download here)
Download # Newest nyar4psg 2.0.0 library for Augmented Reality (*.rar file)
NOTE: Extract library and put nyar4psg folder to Processing libraries location as you can see in example here: “C:\Users\EdgarasArt\Documents\Processing\libraries”. If there are no libraries folder in Processing folder (in My Documents) – create it!
