This?

Yup, I downloaded the files and looked through them, I am completely new to all of this(less than a month of arduino experience, which is my only experience with a microprocessor). Is calibrating the attiny really as simple as just running the Save_to_EEProm sketch and following the instructions?

The documentation is great, I ordered a few attiny85s, the 84s had a 20 dollar handling charge from my local(ish) vendor, next time I have a mail order from somewhere else I'll grab a couple and try those too. Thanks for all of the help.

edit: what terminal program do you favor? I've been searching and it seems like everyone uses a different one, any benefits to a certain one?
