Description
TinyKnob is a rotary encoder with a USB interface based on the ATtiny45/85 and the V-USB software-only implementation of USB1.1 devices on AVR microcontrollers (https://www.obdev.at/products/vusb/index.html). The example code implements a volume control knob for PCs which works without installing any driver by acting like a generic HID device. ![IMG_20200511_174809_x_z.png](//image.easyeda.com/pullimage/HWeS1JOguJcQ5Xr8T44YHmQ3RtwLcEdyvSQHDJp1.png) ![IMG_20200802_171613_x.jpg](//image.easyeda.com/pullimage/IRtl3stloyaAqs243jnQIyJxGwizCU880ZP8mbX0.jpeg) ![IMG_20200820_165124_x.jpg](//image.easyeda.com/pullimage/rlJXNpQRUvVPjmwsQ2jydMUwVpkngSApfFFEzzTb.jpeg) ![license.png](https://i.creativecommons.org/l/by-sa/3.0/88x31.png) This work is licensed under Creative Commons Attribution-ShareAlike 3.0 Unported License.
