Arduino Image Scanner

at 10:04 am. Filed under Complex Hacks, Computer Hacks, Electronic Hacks


The original intent of this project was to make a MIDI device that would scan in low resolution images on paper and play them as music. Turns out that even though it is only using a handful of LDRs (photo resistors) is makes for a pretty good image scanner also.

"It uses LDRs to measure the gray-scale of specific point of a image, and triggers midi notes from a selected threshold. When the threshold is reached the velocity will be set by the darkness at that point. the darker point the higher the velocity will be."

    I love this project, that contraption is a thing of beauty.
    The scan’s very impressive, but what I want to know is – what music did it make?!
