As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

[Long Haired Hacker] has undertaken a high-resolution 3D printer build. He got his hands on some motors to drive the build platform but it doesn’t have a built-in encoder. He knows that optical ...

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 ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

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 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 ...

Hirschmann's new gSENS DWG 20 rotary encoder uses optical sensors to break down one revolution of a shaft, of a hoist or slew drive unit, for example, into 8192 increments. The device then converts ...

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 ...

The PST-360 rotary, through-hole position sensor combines a through-shaft design with 360º absolute position feedback in an extremely thin package. The PST-360 rotary, through-hole position sensor ...
