I have connected as follows - VCC - 5V (because it's GY 521, it has a vol regulator) GND - GND SCL - A5 SDA - A4 AD0 - GND INT - D2

I am using the official I2C Scanner. I have followed this tutorial, Getting started with MPU 6050 sensor

so have installed all required libraries.

What's the error?

No Device found when I run the I2C scanner

Tried to upload the official raw data sketch, but got back 1, -1 Using this example

I have tried these solutions form forums. MPU 6050 Broken? Problem Reading data from MPU 6050

This answer in the forum says to add by level shifters for SDA and SCL, but no tutorial, even the official one, doesn't mention this.

Please help! Much Appreciated! :D
