Hey, I’m trying to incorporate a scroll wheel like [this one into my project. But I have no idea how to connect it to an arduino. I looked at the [data sheet and it mentions ‘Rotational Output Waveform’, I don’t know where to go from there. Any help is appreciated.](http://media.digikey.com/PDF/Data%20Sheets/C&K/TSWSeries.pdf)](http://www.digikey.com/scripts/DkSearch/dksus.dll?WT.z_header=search_go&lang=en&keywords=ckn10345-nd&x=0&y=0&cur=USD)
What you have is basicaly a quadrature encoder. You have two switches that are out of phase by 90 degrees. These can be polled or connected to interrupt pins and using some logic the direction of rotation can be determined. Start by Googling “quadrature encoders arduino”.
