Software Code
Open Arduino IDE.
Download the 3-Axis Digital Accelerometer( ±2g to 16g) from Github. Click on Sketch >
Include library > Add .ZIP library, import the library into the IED.
Copy the following code, click Verify to check for syntax errors. Verify that there are no
errors, and you can upload the code.
In this program, acceleration information is sent from the sensor to Seeeduino via I2C
bus and then Seeeduino printed them onto the serial monitor. Open the serial monitor
to check the result.
