Serial 4 digit seven segment LED display Electronics Lab
The downside is they are resource hungry. For example, it requires 12 I/O pins of a MCU to drive a 4 digit seven segment display using a standard time division multiplexing technique. Here I present a serial seven segment LED display module that can be used with any MCU using a 3 wire SPI interface.
How to Control a 4 digit 7 segment LED Display with a
A 4 digit 7 segment LED display has 12 pins. 8 of the pins are for the 8 LEDs on a 7 segment display, which includes A G and DP (decimal point). The other 4 pins represent each of the 4 digits from D1 D4. The Max7219 pinout should make a lot more sense now. The Max7219 needs about 5V to operate.

Seven segment display Wikipedia
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 widely used in digital clocks, electronic meters, basic calculators, and other electronic devices that display numerical information.

One Digit 7 Segment LED Display
Basic 1 digit seven segment display can show numbers from 0 9 and a few characters. 7 segment displays are of different types; especially they differ in the number of digits/character it can display. Basically a 7 segment display is a single unit, which can display only 1 digit or 1 character.
Adafruit " 4 Digit 7 Segment Display w/I2C Backpack
A fun way to make a small display is to use an 8x8 matrix or a 4 digit 7 segment display. Matrices like these are 'multiplexed' so to control all the seven segment LEDs you need 14 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space.
