The example code implements a volume control knob for PCs which works without installing any driver by acting like a generic HID device.\n\n![TinyKnob_pic1.jpg](https://raw.githubusercontent.com/wagiminator/ATtiny85-TinyKnob/master/documentation/TinyKnob_pic1.jpg)\n\n# Compiling and Uploading the Firmware\n## If using the precompiled hex-file\n- Make sure you have installed [avrdude](https://learn.adafruit.com/usbtinyisp/avrdude).\n- Connect your programmer to your PC and to the ICSP header on the board.\n- Open a terminal.\n- Navigate to the folder with the hex-file (software/binaries).\n- Execute the following command (if necessary replace \"t85\" with your chip and \"usbasp\" with the programmer you use):\n  ```\n  avrdude -c usbasp -p t85 -U flash:w:tinyknob.hex -U lfuse:w:0xe1:m -U hfuse:w:0xdd:m\n  ```\n\n## If using the makefile (Linux/Mac)\n- Make sure you have installed [avr-gcc toolchain and avrdude](http://maxembedded.com/2015/06/setting-up-avr-gcc-toolchain-on-linux-and-mac-os-x/).\n- Connect your programmer to your PC and to the ICSP header on the board.\n- Open a terminal.\n- Navigate to the folder with the makefile (software/sources).\n- Run `DEVICE=attiny85 PROGRMR=usbasp make install` to compile, burn the fuses and upload the firmware (change DEVICE and PROGRMR accordingly).\n\n# References, Links and Notes\n1.
