ATtiny85 Clock

Because I use a lot of tutorials online, I figured I should give something back. So this is my first electronics tutorial, or any for that matter. I should note that I’m not a native English speaker So when I make a mistake or you think something should be a little different, I like to hear it.
In this tutorial I will be building an electronics clock, based on the ATtiny85. Which uses a max7219 to drive the 4-digit 7-segment display and an DS3231 as a Real Time Clock. It is part of a bigger project, it I thought I should start here.”
