I'll be honest from the start of this post: I'm building and arduinoboy. No! Don't hit the back button yet!
The problem I'm having is not getting it to work. I've got that figured out. The issue is not only is it an arduinoboy, but I've also added on more to it to work as a stand-alone midi device with an XY pad and expandable keys. I want to add more, but I'm out of usable pins on the arduino. The biggest problem is the arduinoboy has 5 modes, each with their own led to show the userwhich one he is using. That's five pins plus the status led. On top of that I'm adding two more modes with my own midi controller built on the same arduino, but I dont have enough pins left to show those.
Is there any way more efficient to display the status led plus about 7 modes using 6 pins or less? Does not have to be LEDs. I just have to clearly see which one of seven modes I'm in. I thought about having one led that blinks a number of times per what mode I'm in and then pause. Also, I'm trying to work in a way to display which of 16 midi channels I'm using.
I i should just get an LCD?
