7 Segment LED Display (Single Digit, Common Cathode)

Overview: The Standard Numerical Counter. The Common Cathode 7 Segment Display is a fundamental output device used for displaying numbers (0-9) and some letters. In this COMMON CATHODE configuration, the cathode (negative pin) of all eight LEDs (seven segments plus the decimal point) is connected to a single pin, which is typically tied to GROUND (GND). To illuminate a specific segment, you must apply a HIGH (VCC/5V) signal to that segment's pin. This module is the standard choice for projects driven by positive-logic outputs. Projectile Electronics supplies this component for robust and high-visibility numerical output.

Key Technical Features: Basic LED Output. Type: COMMON CATHODE (Requires logic HIGH to illuminate a segment). Number of Segments: SEVEN SEGMENTS (a to g) plus one DECIMAL POINT (DP). Visibility: High contrast and brightness, easily viewable indoors. Compatibility: Directly connectable to microcontroller digital pins (with current limiting). Pinout: Standard pin configuration for easy breadboard or PCB mounting. LED Color: Available in standard colors (e.g., Red, Green).

Applications: Time and Counting. This display is expertly suited for: Building DIGITAL CLOCKS AND TIMERS, simple EVENT COUNTERS (e.g., scoring displays), displaying SENSOR READOUTS (e.g., temperature/RPM), and use in EDUCATIONAL KITS to teach digital logic and basic interfacing.

Safety Warning and Usage Notes (CRITICAL). This display MUST BE USED WITH CURRENT-LIMITING RESISTORS (typically 150 Ohm to 330 Ohm) on each segment pin when connected to a microcontroller (like Arduino 5V) to prevent permanent LED damage. For driving multiple digits, an external driver IC (like the 74HC595 shift register or specialized LED driver) is required to save I/O pins and ensure sufficient current. Do not connect directly without resistors.

Projectile Electronics Quality and Trust. We guarantee this 7 Segment Display provides BRIGHT, RELIABLE NUMERICAL OUTPUT, making it a stable and durable component for your digital electronics projects.
