Re: Dead simple Arduino MIDI controller for PTT button.
yes of course, but i wouldn't call it a PCB ;)
Just a strip pcb meant for prototyping.
The vertically arranged resistors are for limiting the LED current.
The horizontally arranged resistors are pullup resistors for the VFO A, B and PTT Buttons.
There are 3 KY-040 encoders completely with their own pcb and Button and Encoder Output pins.
I've tried to attach them to pins having interrupts in the arduino to have a better switching sense.
I really would like to extend it to have another bunch of controls on it.
I think a RX=TX (On Off), RX -> TX (Sync) would be cool. I also would like to add a Mode selector.
And the top of my list would be a little display to show the selected value, when selecting something ;)
But it had to be quickly available and it's working flawlessly since nearly a year.
