I am trying to do a self balancing bot as a school project, but I got stuck with the MPU6050.

I tried using the code by Jeff Rowberg (MPU_6050_raw) but it's reading only zeros.

I tried the MPU_6050_DMP and got stuck at "initializing DMP.." and no reading is shown.

I tried other code, but same thing happens, either reading zeros or getting stuck at "initializing DMP..".

And how can I make sure that the chip isn't broken?
