Seven Segment Display Arduino

For a long time I did not post tutorials, because there are busy college and organization, so on this occasion I will post a basic tutorial using seven segments on arduino.

I will explain the seven segment . A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. Seven-segment displays are used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information. Source : Wikipedia
