This week we were introduced to CadSoft Eagle, a program for creating schematics and designing circuit boards.
So far I have been working on adding an electret mic and a Neopixel to my ATtiny85. I would like to make the Neopixel react to sound. Because I'm using two components that already come on breakout boards, I've only added header pins for attaching those parts.
Our teacher Andy gave us a schematic to build a programmer shield for an Arduino Uno. This will plug directly into the pins of the Uno and allow us to upload code easily to the ATtiny (8 pins) and ATmega (28 pins).
After a couple hours of soldering, here is my finished programmer shield
