Hi, I'm planning on building an installation to cover a wall roughly 4mx3m. My original plan was to buy lots of piranha LEDs soldered onto pcbs and tiled onto a wall. These woud then act as a huge low-res display, each LED working as a pixel.
Having usefully discovered (from this forum!) that even a 72x24 res display (1728 leds) wouldn't be possible to build myself using Arduino or any other technologies I must revise my plan:
My idea now is to use much fewer lights (20x10 res so 200 in total). The area is quite well lit and so I would place the lights within light boxes to make the 'pixels' distinct.
So, my questions are:
-What would be the best kind of lights to do this?
-Is there a mains-powered alternative I could control from Arduino or other technology?
Thanks for any advice
