Hi folks, Brand new to Arduino. I need to control 32 individual LEDs that will either blink, be on, or be off depending on which midi note numbers are received...
From what I can tell, I will need the Arduino Mega for this, is that correct? I see the mega has 54 digital i/o. Does that mean I can hook 54 LEDs, or 27?
This will be a project where it will be built and then live inside a rack, so is there any way to use one of the cheaper boards and just add more outputs?
