hey, I am new in arduino and I had a hard time to read the small letters do you know how to get them bigger?
thanks
You can change font sizes in File > Preferences > Editor font size.
You can scale the entire interface in File > Preferences > Interface scale after unchecking File > Preferences > Interface scale > Automatic. You must restart the Arduino IDE before the scale change will take effect.
If those don't do what you need there are additional font sizes that can be set in the theme files. I can provide information on that if necessary.
