Using the RFID reader

We are using the ID-12 rfid reader from sparkfun. When a card is read it just spits out the ID serially on a pin. The atmega168 only has one USART and it is already hooked up to the USB port. You will need to use a software uart to read the ID-12.

Here are some useful links.

• example tutorial that we had working last night(includes simple schematic, code, and needed library)
