7 segment displays are very popular in maker projects. They have just the right balance of vintage appeal with modern functionality.
From Tom’s Hardware:
7-segment displays, the kind found on old digital alarm clocks, can be great for Raspberry Pi projects, including those you make with Raspberry Pi Pico. You can use a 7-segment display to keep score in a game, show sensor data like temperature or distance numbers or to keep track of time. You can even show some letters.
