I happened to have everything on hand to build one and I got tired\nof using and wiring up a breadboard to do this, so I built this shield.\n\n## Building\n\nUse whatever method you prefer for building the pcb. Along with the Eagle files\nI've included a PDF you can print for the toner transfer and photo-resist methods.\n\nYou'll need:\n\n* Some pcb and a method to etch or mill it\n* 10uF capacitor\n* 8 pin dip socket\n* pin headers suitable for an arduino shield\n\n\n## Programming\n\nFor this, I assume working with the Arduino IDE. Anything else and you're on\nyour own.\n\n1. Load the ArduinoISP sketch (File -\u003e Examples) onto your arduino.\n2. Set the board to be ATtiny85 (internal 8MHz clock).\n3. Set the programmer to be Arduino as ISP\n4. Put the shield on the arduino, stick an ATtiny85 into the socket\n5. If it's the first time you've programmed the chip, run Burn Bootloader\n6. Write your arduino code and upload it as normal.\n7. Use your newly programmed ATtiny85!\n\n## License\n\nThis work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.\n\nhttp://creativecommons.org/licenses/by-nc-sa/4.0/deed.en_US\n\n## Contributing\n\nGot feedback or fixes?
