ATTiny85 + micronucleus using an AVR programmer
This gist is a list of instructions that I used to program my ATTiny85s with Micronucleus. They worked for me, but your mileage may vary! I would highly recommend starting by looking at the SparkFun article linked at the bottom for schematics and more in-depth info. This gist is mostly just a copy/paste list.
## Required:
- ATTiny85
- AVR programmer
- 1 uF capacitor
- Micronucleus FW: https://github.com/micronucleus/micronucleus/releases
- avrdude: http://www.nongnu.org/avrdude/
## Setup:
