Hello,
This is certainly a basic question and I apologize.
For a MIDI controller project, I have many switches plus many LEDs (64).
When the LEDs are all on, the current draw exceeds Teensy specifications.
I would like to control the LEDs with multiplexers.
Can I use a bunch of CD74HC4067 to drive the LEDs ? Can they support driving 16 LEDs ?
How can I power the multiplexers to deliver enough current ?
If I am on the wrong path, how do you deal with multiple LEDs ?
