If you have ever tried to use a raw, non-multiplexed 4-digit display, you know the pain. It requires roughly 12 to 16 digital pins and a handful of transistors or shift registers to manage the scanning. It is a headache for beginners and experts alike. arduino tutorial 64
A typical 2-digit 7-segment display has 18 pins: // Arduino Tutorial 64 - Basic Counter #include <Arduino
Because each digit is active only 50% of the time, you may need to increase current slightly—but resistors prevent damage. non-multiplexed 4-digit display
