Knob controllers can control volume settings, scroll through web pages, and help edit movies among other uses. You can buy a commercial one from Griffin Technology for $45 or build one yourself with ...

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 ...

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 encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...

A new combined interface for Optocode absolute rotary encoders allows simultaneous communication of both absolute and incremental rotary position data. The interface provides cost-effective ...

[Blake]’s interest in building keyboards happened naturally enough — he was looking for a new project to work on and fell into the treasure chest that is the mechanical keyboard community. It sounds ...

The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

austriamicrosystems has announced the AS5050 10-bit magnetic rotary encoder IC for contactless position sensing with the industry’s lowest power and smallest size. austriamicrosystems has announced ...
