Using encoders without pushbutton? about encoder HOT 2 OPEN

After some further thinking and researching, I think I have some solutions to my problems...

Option One: this Arduino Micro board I have actually has way more digital pins that I can use than I initially thought...so I may just end up hooking up the pushbuttons regardless!

Option Two: Even if I didn't want to use the pushbuttons, I still could just pass a digital pin that is in use for a different component into the constructor for the Encoder object in order to properly create it, and then I could just do nothing with that data regarding the encoder operation. Just because I assign a pin to create the object doesn't mean I have to use it, and I don't think that will mess up operation of any other component/code that actually IS utilizing that pin, that should all continue to work correctly. Let me know if my train of thought checks out there.

Thanks again!

Hi,

I think you have answered your own question!.

Indeed, you can pass any input pin as the pushbutton, and then just not use it with the library. The encoder should work just fine.

Or better yet, you can even use any pushbutton you already have in your project that you want to debounce, and pass it to the Encoder library even if that button is not physically attached to the Encoder. By calling encoder.button() you will still get the debouncing effect applied to that button. Maybe that's also useful for you in case you have a button with critical operation that needs to operate in a 'clean' way.
