I want to use the MPU6050 on GY521, but Ardunio Uno does not find it.
I connected as described in several threads here in the forum.
3.3V - VCC
GND - GND
A5 - SCL
A4 - SDA
I read http://playground.arduino.cc/Main/MPU-6050
I tried i2c_Scanner.
The function Wire.endTransmission delivers error = 2 (received NACK on transmit of address).
What does this mean?
Any help is appreciated.
