- Arduino Uno
- Jumper wires
Connecting the Hardware
Installing a library
In the Arduino IDE, click Sketch->Include Library. Select “Manage Libraries…” as shown below.
Filter your search by typing ‘MPU9250’. Look for Bolder Flight Systems MPU9250 by Brian Taylor. Click on that entry, and then select Install.Then search MPU9250 and click to install as shown below
Upload the sample sketch
open the sample sketch that is located in file>examples>Bolder flight systems MPU9250>Advanced_I2C. and upload it. as shown below
Testing the circuit
Open the serial monitor – this is what I saw, it took a little bit of time for the readings to appear
