This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...

If you’ve ever spent time in a modern BMW, you’ve probably fussed about with the goofy iDrive controller. It’s a rotary knobbery slidery thing that just never really feels that good to use. [Garage ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

A DIY rotary inverted pendulum you can print, solder, and train at home — for about £20 in parts. It's an open, hackable take on the rigs you'd usually buy from a lab-equipment vendor (Quanser's QUBE ...

Rotary encoders connect to a shaft and, as the shaft rotates, the encoder outputs pulses. These are used to determine the speed of the object. By counting the amount of pulses per one full turn of the ...

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 ...
