I was thinking how could I make this happen:
Connecting 4x4 led buttons to teensy to use as step sequencer. The leds would on/off when button is pushed. That is something I think I could do pretty easily.
But I would want the leds to be two color leds. Green led would light when pushing the buttons. Red color would show the sequence going forward the steps. How would I get the leds work like this?
Better to just connect the 4x4 to the axo and use the teensy for other inputs and Outputs? Or wire buttons and leds to teensy and just the red pin of the led to axo? Don't know if it's even possible to wire like that
