Ok, so here's what I'm working on: it's a light-up cityscape painting. It's an antique and used to have those blinking christmas lights in it, but I decided to run it through an Arduino so that I could control individual channels, etc. There are:
19 amber superbright LEDs (these are on all the time and follow along a street on the painting) 13 green superbright LEDs (these are on all the time and form a straight line (along a field) 10 blue superbright LEDs (these need to fade randomly on and off and are scattered around the painting)
I've got my Arduino hooked up to a TLC5940, and I was playing around with this thread to try and figure out the random fades: http://arduino.cc/forum/index.php/topic,70947.0.html. Now, the question is "how the heck do I wire all this stuff up?", so here are my questions:
2) Thought on enclosure? I was thinking just wiring the TLC5940 and all the output wires, resistors, etc to a breadboard and then having that attached to the Arduino inside a project box, and then adding grommets to the outside for all the wires (since they'll need to be run all over the back of the painting). Any better ideas on how to make it a bit more organized or cleaner? I may just run all the wires, hot glue them down, and then cover the entire back with black felt or something. Maybe have the project box connect to the back with some kind of ribbon connector (so that you can unplug the project box if need be)? I don't know.
