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 ...

Touchscreens and touchpads haven’t totally taken over the human-machine interface (HMI) function and many situations still exist where discrete switches or even the classic QWERTY keyboard remain the ...

Optical rotary encoders, sensors used everyday in industrial applications, provide instantaneous and continuous data on rotational motion. Designed to monitor speed, position, distance, and direction ...

Tailored for battery operated apps, the AS5055 magnetic rotary encoder with automatic power-down and wake-up modes integrates four Hall sensor elements, a 12-bit angle encoder, smart power management ...

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 ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

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 ...
