Dial

A dial is a device or component that enables precise adjustment or control by turning a knob, pointer, or indicator. Typically found on equipment like radios, microscopes, or control panels, dials translate rotational movements into changes in settings such as volume, intensity, or focus. They provide an intuitive way to fine-tune parameters, offering tactile feedback and visual cues for accurate adjustments. In essence, a dial helps users regulate a specific aspect of a device’s operation in a straightforward and controlled manner.
