What it does

The 7 Segment Display is a numeric LED display showing digits 0-9 and some letters using seven illuminated segments. Essential for clocks, counters, scoreboards, and simple numeric readouts in embedded projects.

Key features

  • Standard 7-segment numeric display
  • LED-based bright and clear digits
  • Common cathode or anode configurations
  • Low power consumption per segment
  • Wide viewing angle
  • Available in multiple sizes
  • Easy to drive with shift registers or dedicated ICs

Good to know

  • Use current-limiting resistors (220Ω typical) on each segment
  • Common cathode: ground common pin, drive segments HIGH
  • Common anode: power common pin, drive segments LOW
  • For multi-digit displays, use shift register (74HC595) or MAX7219
  • Brightness controlled by current or PWM duty cycle
