Microchip has introduced a touch controller family for ‘knob-on-display’ (KoD) human-machine interfaces. These interfaces add a physical ‘clicky’ knob to the front of a display without traditional ...

Rotary potentiometers, switches, and encoders all share a basic design: adjustment is done via a shaft onto which a knob is attached, and knobs are sold separately. That doesn’t mean one knob fits all ...

Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen ...

An inductive sensing based incremental encoder knob design can provide a robust and low-cost interface for control inputs. It can reliably operate in environments which have dirt, moisture, or oil ...

Integrating touchscreen and rotary-knob control into a single IC simplifies combining these two different but complementary user-input devices. Touchscreens and touchpads haven’t totally taken over ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...
