The gyroscope sensor measures the angular velocity. The external I2C bus is for connecting external sensors. They move inward and outward simultaneously in the horizontal plane. This causes the yaw angle to change hence it is called Yaw Mode. Then connect the VCC to Arduino’s 5V, X to Arduino's Analog Pin A5, Y to Arduino’s Analog Pin A4, and Z to Arduino’s Analog Pin A3. You will notice that the majority of this sketch is exactly the same as the previous sketch, except: Copyright © 2020 LastMinuteEngineers.com. All these problems are solved by combining an accelerometer with a gyroscope sensor. Before using the device object you constructed, you must initialize it with the sensitivity range you want to use. This causes the roll angle to change hence it is called Roll Mode. MPU6050 can be programmed to raise interrupt on gesture detection, panning, zooming, scrolling, tap detection, and shake detection. Finally, we output the values on the serial monitor.
