Hey all,


I'm trying to get my MPU-9150 to work with my Arduino UNO, but when I load up the I2C scanner, it doesn't detect any devices at all. I obtained the scanner from below:



I've connected it in the following fashion:


Arduino - MPU9150

3.3V - VCC


A4    - SDA

A5    - SCL

Digital2 - INT


I haven't soldered the connections, they're in my breadboard. 


What could be causing the scanner to not detect any devices? Maybe the connections themselves aren't secure and I need to solder them, or maybe a faulty wire? 


Any help would be appreciated :)
