Disable the Uno internal pull-ups, wake the chip, choose the ±2g accelerometer range and print ax, ay and az in g. Use the Uno R3 Learning Kit. Build with power disconnected, check the labelled connections, then upload the supplied sketch. Drag or zoom the 3D model to inspect it from any angle. ### Identify your part This lesson targets a regulated GY-521 with I2C pull-ups to 3.3V. Verify the supplied board; the bare MPU6050 is not 5V tolerant. ### Also needed The header must be soldered securely; this build plugs its eight pins directly into the breadboard.
