sgulati3 Posted February 7, 2015 Report Share Posted February 7, 2015 Hey all, So I'm connecting my MPU6050 to an Arduino micro running the DMP Example code however, every time it says that the mpu connection fails! I ran the i2c scanner to see what address the MPU6050 was in but it says no devices found. I'm not sure what I'm doing wrong. I have the following pins connected: VIN to 5V (also tried 3.3V) GROUND to GROUND SDA to A4 SCL to A5 We've also tried INT to D2. Pictures of my breakout board and overall setup are below. Do you have any idea what could be causing this to go wrong. The light on the MPU lights up so we know that electricity is flowing/it's connecting.

kkuisma Posted February 22, 2015 Report Share Posted February 22, 2015 I think you are using wrong pins for I2C. Arduino Micro has ATmega32u4 and I2C is on digital pins 2 (SDA) and 3 (SCL), not A4 and A5. Quote Link to comment Share on other sites More sharing options...
