360 Degree Rotary Encoder Module

This rotary encoder module turns a simple twist-and-click knob into a versatile input device for menu navigation, volume control, and value-adjustment interfaces. Unlike a potentiometer, it reports discrete clicks of rotation rather than an absolute voltage, so a project can keep counting up or down indefinitely without hitting a mechanical end stop, which makes it well suited to scrolling through long menus on a small display. The built-in push-button, triggered by pressing straight down on the shaft, doubles as a confirm or mode-select input without needing a separate button wired in. It is a frequent choice for DIY audio volume knobs, 3D printer control panels, synthesizer and MIDI controller builds, and any interface that benefits from tactile, click-based input rather than a smooth analog dial.
