Volume Knob for Digispark ATtiny85

thingiverse

I've created a new USB Volume Knob, that fits for a simple rotary encoder and a Digispark ATtiny85 with micro USB. If you have a rotary encoder with 20mm half handle, to avoid the volume knob is becoming very high, the semicircular mount on the rotary encoder must be shortened by approx. 4mm.On the aother hand, you can take a rotary encoder with 15mm half handle. You can find instructions, the sketch and the wiring diagram under: https://learn.adafruit.com/trinket-usb-volume-knob/wiring You also need: Digispark: https://de.aliexpress.com/item/1005002116780368.html Rotary encoder: https://de.aliexpress.com/item/10000056483250.html 2x 4x2mm Screws to tighten the Digispark 4x 10x2mm Screws for the bottom plate. Note from the community: As alternative to the half handle, I added a knob for toothed shaft aka plum handle.
