how do we connect the GY-521 gyro+accelerometer and serial read from arduino about the ' angle & acceleration. I am not building any project with it at moment but would like to make my sensor work and read its data first.
Ni hao Soni,
Start by downloading the datasheet. Read it!Post a link to it so we can read it. Tell us some basic information like is it I2C, ISP or what? Go to the Arduino site and read the instructions for using the I2C or ISP library.
