Where is my wire.h file

[shanren]

Hi,
I used wire.h in my code, but did't find where the file located, why?
Thanks

Because you didn't spell "Wire.h" correctly. It has to be 'Wire', not 'wire'

The actual file for the AVR boards is at (on my Win 10 machine):

...\Arduino 1.8.19\hardware\arduino\avr\libraries\Wire

If you have other boards installed the file may be elsewhere.
ATTinyCore:

...\AppData\Local\Arduino15\packages\ATTinyCore\hardware\avr\1.5.2\libraries\Wire

ESP32:

...\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.2\libraries\Wire
