I am painfully new to Arduino (my very first project was just a few weeks ago for my studio class ), so do forgive me if I struggle with stupid things or if this is the wrong forum.
Anyway, for my final project in my interactive viz studio, I'm making a small starscape with different modes (all off, twinkly, all on, etc) and roughly 80-100 LEDs and an IR sensor to notice when someone is touching it. Here's the general concept:
I don't actually want to control each LED individually; instead, I want to put them in groups of 8 to 10 to make managing the light patterns easier. My first assumption would be that I ought to put the LEDs in each group in parallel. If that's right, then my next question: What's the simplest/best way to power that many LEDs (current count on my illustrator file is 80, could still grow)? At some point, every light in the panel would need to be on simultaneously.
Any advice here, or if you know of a nice/straightforward? tutorial, that would be great.
