How to Solder: Through-
Hole Soldering
This tutorial covers everything you
need to know about through-hole
soldering.
Serial Peripheral Interface
(SPI)
SPI is commonly used to connect
microcontrollers to peripherals such
as sensors, shift registers, and SD
cards.

main embedded communications
protocols in use today.

Hardware Overview

The H3LIS331DL breakout is fairly simple.
H3LIS331DL Sensor IC - This is the sensor IC. Its operating voltage only
extends up to 3.6V, so to use it with a 5V Arduino or Arduino clone, you'll
need some kind of voltage translation! It is perfectly centered on the PCB.
Installing an Arduino Library
How do I install a custom Arduino
library? It's easy!
