0.56 Inch 1 Digit Red 7 Segment LED Display 10 Pin

0.56 Inch 1 Digit Red 7 Segment LED Numeric Display Common Cathode 10 Pin

The 0.56 inch single digit red 7 segment LED display is a compact numeric indicator designed for electronic measurement and control systems. It provides a clear and readable numeric output using seven individual LED segments arranged to form digits 0–9. Due to its low power consumption and simple interface, the display is widely used in Arduino projects, digital counters, clocks, panel meters, and student learning kits. Many tutorials at Bigyan Project also use this type of display for basic electronics education and microcontroller practice.

This display uses a Common Cathode configuration, meaning all LED cathodes are internally connected together. Each segment is activated individually by applying a positive voltage to its corresponding pin through a current-limiting resistor. The bright red AlGaAs LED chips provide high contrast visibility even in indoor lighting conditions, while the standard 10-pin DIP layout allows easy installation on PCB boards and breadboards.
