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 ...

[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 ...

As wonderful as mechanical keyboards are, most of the pre-fab and group buy models out there have zero media controls. If you want rotary encoders and OLED screens to show what function layer you’re ...

If you would like to add programmable controls via touchscreen and rotary dials to your existing project or next home automation system the M5Dial might be worth more investigation. Its interactive ...

Encoders are critical to the production of advanced electronics, one of the fastest growing and advancing industries in the world. Rotary, angle and linear encoders are all used in one form or another ...

POSITAL’s high-performance IXARC optical rotary encoders are now available with EtherCAT communications interfaces. EtherCAT (Ethernet for Control Automation Technology) is a special form of ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

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 ...

Rotary encoders provide critical information about a motor shaft’s position, rotational direction, velocity (rpm), and acceleration. They are vital components in motion-control feedback loops used in ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...
