I honestly have no clue what keyboard.h is or does it is just in every bit of code I have found or in every answer I have seen. I already have 1 working model but I lost the original code for it. it definitely used digikeyboard.sendkeystroke when I didn't it and it didn't use keyboard.h.
after removing the quotes it has stopped the first issue I have no idea what to do about the second though. it seems I cant do anything with the attiny85 until the issue is fixed because it is across all the attempts I have made.
