Nerdy Birthday Card
Welcome Nerds and Happy Birthday! You are visiting this page because some awesome person gave you a Nerdy Birthday Card :) Use the switch to turn on your Nerdy Birthday Card. It will display "Happy Birthday!" (or a custom message if ordered) and play a song. After the song is complete, the display will tell you to make a wish and blow out the candle. Blowing on the candle (yellow LED/microphone) will extinguish the candle. Finally, the display says "Have a Wonderful Year!" You can also write the name of the birthday person on the back. A fine tip sharpie marker works best.

As of October 15, the latest version of the Nerdy Birthday Card is v1.3. Only a handful (~20) of v1.1 and v1.2 were sold as the prototypes. Mostly everyone will have v1.3. You can find the version number on the lower bottom of the back of the card. The versions are almost identical and the code runs exactly the same on all versions. The two differences in v1.3 is that the button was repurposed from being a reset button to being an input button, which is tied to the same line as the microphone. And the second difference is that the ICSP port is now through-hole instead of SMT.
