Specifications :

Common Cathode (CC)

In a common cathode display, all cathode pins are connected together and LEDs are controlled via an anode terminal. It means to turn ON the LED (segment), we have to apply proper voltage to the anode pin.

The following demonstration will show the working of the above configuration:

Pin Diagram

• The 7-segment display has a total of 10 pins.
• The common pin (com) is connected either in a common anode or a common cathode configuration.

Resistor Connections

• We have to connect the resistor to each segment individually.
• Avoid LED’s connection in parallel with one resistor, because each LED segment doesn’t have the same forward voltage drop.
• If we connect one resistor to the parallel LEDs then some LEDs will glow and some will not. Because forward voltage drops are different for each LEDs, LEDs which are having lowest voltage drop across them will only glow. And though if we connect LEDs with ideally equal voltage drop, the current will get divided and brightness will get affected each time while switching the LEDs.
