Example Code for Arduino-Read Acceleration

Hardware Preparation

• Firebeetle Board-M0 × 1
• H3LIS200DL Triple Axis Accelerometer × 1
• 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

Sample Code
