Have you found yourself in a maze of twisty-turny knobs, all alike? These micro potentiometer (or rotary encoder) knobs offer a rainbow burst of color to your synth or control panel. They are made of a hard plastic, with a grippy star shape. The shape is sometimes referred to as "Davies 1900" style, but they may not be a perfect size/color match for original Davies knobs.
The micro knobs work with any shaft type (round, D-shaft, or T18) because they come with a tiny lil set screw. Use a 2mm hex wrench, not included, to carefully tighten once placed.
This is the Adafruit black version, comes in a pack of four! We have many other colors available as well.
Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
