I thought it may be of interest to have a place for neat now (or old) parts.
This is what I spotted today:
An I2C rotary encoder.
www.adafruit.com
The price is $5.95 US for the board.
This makes it easy to add an encoder to your projects. In fact, up to 8 encoders can be strung together on the same I2C lines.
At the moment, Adafruit are out of stock, and the boards do not come with the encoder.
Each board has 3 address links to allow for the 8 devices, and they also have an Neopixel addressable RGB LED.
Adafruit publish the driver code for a number of platforms too.
The board needs to be polled for the encoder reading or button push, but an IRQ line can be used to indicate an event if needed.
I like these devices. It would make it easy to add various controls to a front panel.
And different encoders could be used to drive the boards if better quality is the aim.

Adafruit I2C Stemma QT Rotary Encoder Breakout with NeoPixel
Rotary encoders are soooo much fun! Twist em this way, then twist them that way. Unlike potentiometers, they go all the way around and often have little detents for tactile feedback. But, if ...
