Basic Operation
-
In a common cathode display, all cathode pins are connected to ground.
-
To light a segment, apply a HIGH voltage (logic 1) to the corresponding anode pin.
-
By turning on different combinations of segments (A to G), you can display numbers 0-9 and some letters.
Applications
-
Digital clocks and timers
-
Electronic meters and counters
-
Scoreboards
-
Simple numeric displays in embedded systems
-
Educational projects and prototypes
