= Description =
The MPU-6050 is a sensor that combines a 3-axis gyroscope and 3-axis accelerometer. Here it is used as the GY-521 module that can be directly connected to the ESP32/ES8266.
The module is connected via the I2C bus.

* https://invensense.tdk.com/wp-content/uploads/2015/02/MPU-6000-Datasheet1.pdf (Datasheet)

= How to connect it electrically =
The MPU 6050 is connected to the I2C bus. This is the same as where the display is connected.
* Pin15 is SCL (OLED_SCL)
* Pin4 is SDA (OLED_SDA)

[[File:Hc-sr04-e.JPG|x420px]]

= Required Module and Files =
* We use two modules:
** '''[https://www.sketching-with-hardware.org/files/imu.py imu.py]'''
** '''[https://www.sketching-with-hardware.org/files/vector3d.py vector3d.py]'''
* this is downloaded from https://github.com/micropython-IMU/micropython-mpu9x50
* the original files are at
** https://github.com/micropython-IMU/micropython-mpu9x50/blob/master/imu.py
** https://github.com/micropython-IMU/micropython-mpu9x50/blob/master/vector3d.py
