When I first got my ATtiny2313 it took me the better part of 4 hours to finally get it programmed. I went through countless tutorials online that were old and outdated. I was never able to get the correct files from one website. I had to combine the files from several websites before I was finally able to program my ATtiny.
NOTE: With the recent update of the Arduino IDE I can't figure out how to get the boards to show up in the list. I'm sure it's easy and I'll figure it out in a bit. For now you are still going to have to use the old version of arduino for programming any ATtiny chips.
The goal of my (Current and Updated!!!) series is to find tutorials online that are old, outdated, or nonworking and make a new tutorial that I have tested and used myself.
My first i'ble in this series is how to use IR remotes to control your Arduino.
I will keep updating my i'bles in this series to work with new Arduino boards, IDEs and the like.
Now I've never tested this process on a windows but I know that it works on a mac. It should be the same for windows, just delete any mac content in the zip.
