Hi guys,
Seems like you're all friendly here from the other posts I've read, hopefully you can help me out.
TL; DR at the bottom.
I've built an Arduino powered macro keyboard, it has a few buttons on it which when pressed send a key command to my pc which are then intercepted and processed by autohotkey.
I want to add a volume knob to this setup but can't find the correct type. It should be like a button in terms of its output, as in each click in one direction is a button push, and each click in the other direction is a different button push. Ideally when not being turned it's grounded, however that isn't necessary.
The main requirements are:
- Each turn in one direction has the exact same output no matter how many times it has been turned.
- there's no limit to how many times it can turn (like there is with a pot).
- Turns both ways, each having a separate output.
The reasoning for this method over a pot, is that the pc volume could vary from what the pot's value represents on plugging in, either resulting in limited adjustment or a sudden volume change, neither are nice results.
I know such a switch is out there, as it is in use on my radio, but finding one online has proved tougher than I imagined, likely since I don't know what it's called.
TL;Dr: Rotating switch, like a potentiometer, except each click of the knob sends out a signal as if it were a button.
