Example Code for Arduino-M0-Read acceleration of x, y and z

Hardware Preparation

• Firebeetle Board-M0 × 1
• LIS331HH Triple Axis Accelerometer × 1
• Some Jumper wires

Software Preparation

• Arduino IDE
• Download and install the LIS Series Library and Sample Code （About how to install the library?)

Wiring Diagram

Connect your sensor to an M0 controller (or others) according to the connection diagram below.

Other Preparation Work

• Select getAcceleration.ino.
• Program Burning.
