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 a great addition to many projects. However, controlling them typically requires several pins, interrupts, and debouncing. Thanks to this device, a rotary encoder can be easily ...

The scroll wheel might be the best thing that happened to the computer mouse since, well, the computer mouse. But sometimes you want something a little more tangible. For example, with a ...

This project implements closed-loop position control of a Pololu 70:1 metal gearmotor (4754) using an Arduino UNO R4 WiFi and a Pololu Dual G2 High-Power Motor Shield 24v14 (M1). A panel rotary ...

[Mitxela]’s repair of a Roland JV-1080 (a rack-mounted 90s-era synthesizer) sounds simple: replace a broken rotary encoder on the front panel. It turned out to be anything but simple, since the part ...

Rotary encoders are typicallyused in positioning systems withservo feedback in which the cost of theencoder usually is of minor importance.Encoders, however, are also usedin user interfaces to encode ...

Waveshare MK20 is a multifunctional macro keyboard with twenty mechanical keys featuring 0.85-inch LCD keycaps. As an upgrade to the earlier MK10 model, ...

What a lovely idea for a human-machine interface component – a dumb mechanical rotary encoder knob that simply glues to the front glass of a touch display. All the smarts are in the touch controller.

In a nutshell: Canadian hardware maker Ploopy is now accepting pre-orders for its latest input device. The Ploopy Knob is a 3D-printed, open-source rotary encoder featuring a high-precision sensor ...
