Component Introduction
The four-digit segment display is an 4x8-shaped LED display device
composed of 32 LEDs (including four decimal points), these segments
respectively named a, b, c, d, e, f, g, h, dig1, dig2, dig3, dig4. It is very
similar to the previous 7-segment display, but has four dedicate common pins to control each
digit separately.
