I am attempting to add ATtiny in the boards manager. I've tried adding both:
https://github.com/SpenceKonde/ATTinyCore.git
https://drazzy.com/package_drazzy.com_index.json
to the additional boards manager in settings, but then when I go to search for them in boards manager nothing shows up. Do I need to wait until I have the Atiny phyiscally plugged in? Or are these just out of date? I'm using IDE 2.2.1. Thanks!
EDIT: It worked! I followed this tutorial: https://www.instructables.com/How-to-Program-an-Attiny85-From-an-Arduino-Uno/\
