Introduction
The GPS Alphanumeric Clock is the clock you never have to set! Using UTC time and date we are able to parse out the local time using a Gregorian date calculator and some rules for US daylight savings time (DST). Calculating what day of the week it was on June 7th of 1983 is actually a bit of a challenge. Similarly, figuring out if we were or were not is DST for any given year was not as easy as you might think. This tutorial gives a good breakdown of how to calculate day of the week from any date and a simple way to make your clock set itself (assuming you know the date).

GPS Basics
The Global Positioning System (GPS) is an engineering marvel that we all have access to for a relatively low cost and no subscription fee. With the correct hardware and minimal effort, you can determine your position and time almost anywhere on the globe.
Installing an Arduino Library
How do I install a custom Arduino library? It's easy! This tutorial will go over how to install an Arduino library using the Arduino Library Manager. For libraries not linked with the Arduino IDE, we will also go over manually installing an Arduino library.
What is an Arduino?
What is this 'Arduino' thing anyway? This tutorials dives into what an Arduino is and along with Arduino projects and widgets.
