Adafruit 7-Segment Display
Best easy to use display for microcontroller projects.
This is the ultimate shortcut for adding a classic numerical readout to your projects without the wiring headache. By offloading the complex multiplexing to a dedicated driver, it turns a tedious soldering project into a simple plug-and-play experience, though you do sacrifice the granular control of a raw, unbuffered display.
