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: http://playground.arduino.cc/Main/I2cScanner I've connected it in the following fashion: Arduino - MPU9150 3.3V - VCC GND - GND 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
