Here we discuss the basics of connecting a four-digit, 7-segment display to an Arduino. For those applications 7-segment led displays exist that can supply the desired visual output. Sometimes it is functional and pleasant to display Arduino sensor data on a no nonsense, high contrast numerical display instead of a lcd display or a small graphical screen.
