This is a 5611AS library for arduino
The 5611AS is a single digit LED 7-Segment-Display.
About the pins: You have an upper row (1) and a lower row (2) going from left to right. 1.3 and 2.3 are always GND. The int array goes as follows: 1.4, 1.5, 2.4, 2.2, 2.1, 1.2, 1.1, 2.5! With this simple library you can set all single digits from 0-9 as well as clear the Display.
The library was tested and worked in 3.2018.
