 Rotary Trinky. It is a USB plug-and-play rotary encoder board that also has a Neopixel for feedback and a capacitive touch for additional input. This sends USB HID commands. I can adjust that frame forward, frame advance, one frame at a time. I programmed this to turn on closed captioning when I click the little button. I've also set the cap touch slider as a play pause. It is the Rotary Trinky. It's a USB rotary encoder that plugs right into your computer and allows you to use a rotary encoder, click and touchpad.
