Accelerometer Pi Zero

Accelerometer + Pi Zero

Overview This tutorial involves wiring the H3LIS331DL accelerometer to the Raspberry Pi 0, as well as implementing the code in python that executes the readings. This specific accelerometer is 3-axis, meaning it records data in the x, y, and z-planes, and can take readings up to +-400g’s. Once the sensor is wired to the pi,
