What is the difference between common anode and common cathode 7-segment display?
Common Anode displays have all the LED Anodes connected together and need a display driver with outputs which become low to turn each segment on. Common Cathode displays have all the LED cathodes connected together and need a driver with outputs that become high to turn each segment on.
What will be seven segment code for displaying 7 in common anode display if order is Gfedcba?

| 7 | 0000111 | 07 |
| 8 | 1111111 | 7F |
| 9 | 1001111 | 4F |
What is common anode and common cathode?
There are two types of LED 7-segment displays: common cathode (CC) and common anode (CA). The difference between the two displays is the common cathode has all the cathodes of the 7-segments connected directly together and the common anode has all the anodes of the 7-segments connected together.
What is common anode and common cathode display?
How do you connect common anode 7-segment display to Arduino?
Seven segment display pins connection with arduino are given below.
- Pin 13 of arduino is connected to pin ‘a’ of 7 segment display.
- Pin 12 of arduino is connected to pin ‘b’ of 7 segment display.
- Pin 11 of arduino is connected to pin ‘c’ of 7 segment display.
Which one is better common cathode or common anode?
If the digits are not multiplexed, common cathode is better. 7 (or 8 with decimal point) cathode drivers are needed per digit and one anode driver. If the digits are multiplexed, and there are less than 7–8 digits, common cathode is better.
What is meant by common anode?
Common anode is used in the seven-segment displays. This is an electronic display device which shows decimal numerals. They are widely used in digital clocks and meters, etc. In these displays, all the anodes are connected to one point, and it becomes a common anode.
