sir can u plss help me with my project self balancing robot.. i downloaded a code at github but theres an error using wire.h

Post the code (using code tags; read the sticky ‘how to use the forum’ to see how).
Post the error message that you get.

And modify your Original Post to give it a sensible Title such as "Problem with self balancing robot"

Putting a Forum member's name as the Title is just ridiculous.
