Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

He’s converted a mouse into a tuning dial. The scroll wheel on a mouse is nothing more than a rotary encoder, and can easily be used as a sort of tuning knob. Replacing it with a better encoder ...

LILYGO T-Embed SI4732 is an ESP32-S3 development board with an AM/FM radio, a TFT display, a rotary encoder, a built-in ...

I needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see around. Not the finest encoder in the land, I’m sure, but it should do the job.

For example the they should all share an IO device such as a 23017 or an 8574, or if on arduino pins, all the A pins must be interrupt driven. Secondly, there is a hard limit on the number defined by ...

The design approach of the encoder circuit uses a combinational logic circuit. The encoder circuit is then modelled using simulation and prototype techniques. The simulation model is realized using ...

Abstract: This paper presents a single-excitation absolute capacitive rotary encoder that is small in size ... which are caused by manufacturing, circuit, and installation errors. A prototype is ...

You can refer to the image below for a clearer view of the circuit connections and placement in the helmet. All the modules are powered with 5V from the Arduino. Below is the assembled image of the ...

Pinefeat has designed an EF/EF-S lens controller and adapter for the Raspberry Pi HQ Camera, compatible with Canon lenses, and implementing full electronic control of autofocus and aperture. Canon EF ...

Sim racing often encounters USB-related issues during use. However, with proper USB handling and wiring practices (like grounding and EMI isolation), most problems can be avoided or resolved. ⚠️ Note: ...
