Gentlemen

Today I tried out my GY-521 6DOF.

I ran the I2C code, and the adress was 0x68 [running the board on 5V]

I used Krodal's code to run the gyro, and I seem to be getting really unstable signals:

Just look at the gyro feedback, this is just by tilting it...

MPU-6050

Read accel, temp and gyro, error = 0

accel x,y,z: 12928, -6376, 6420

temperature: 22.341 degrees Celsius

gyro x,y,z : -1201, -219, 814,

MPU-6050

Read accel, temp and gyro, error = 0

accel x,y,z: 8204, -10208, -8428

gyro x,y,z : -6531, -13742, 6892,

MPU-6050

Read accel, temp and gyro, error = 0

accel x,y,z: 12260, -10812, 2188

gyro x,y,z : -2779, -5582, 511,

MPU-6050

MPU-6050

Read accel, temp and gyro, error = 0

accel x,y,z: 17116, -8, -2696

gyro x,y,z : -138, -77, 63,

MPU-6050

Read accel, temp and gyro, error = 0

accel x,y,z: 17032, -36, -2756

gyro x,y,z : -123, -51, 111,

MPU-6050

Read accel, temp and gyro, error = 0

accel x,y,z: 17084, -24, -2648

temperature: 22.482 degrees Celsius

gyro x,y,z : -125, -62, 104,

MPU-6050

Read accel, temp and gyro, error = 0

accel x,y,z: 17000, 0, -2616

temperature: 22.435 degrees Celsius

gyro x,y,z : -151, -64, 74,

Am I misinterpreting the gyro signal? Is this degrees? Why is it so unstable?

I am running my arduino on USB power, is this the issue?

Kind regards
