Seven Segment Display Seven segment displays are used to indicate numerical informationSeven segment displays internally consist of 8 LEDsIn these LEDs, 7 LEDs are used to indicate the digits 0 to 9 and single LED is used for indicating decimal pointGenerally seven segments are two types, one is common cathode and the other is common anode
