I can't connect with serial monitor.... when I connect my arduino with my PC, and open the serial monitor
(of course I exactly connected MPU6050 with my arduino and uploaded MPU6050 library to the arduino . MPU6050 library has no problem.) this message comes....

initalizing I2C devices....
testing device connections....
MPU6050 connection failed
Send any character to begin DMP programming and demo:

I download MPU6050 library and I2C library. And I moved the files to my arduino library files.

But it did't work. I can't find out why connections failed and what should i do. so can you help me?

And I'm korean student, so my english grammer and expression is awkward. please comprehend...

I don't understand why your title says "serial monitor" as that seems to be working properly.

Post you program.
