When the power is given to all the segments, then the number 8 will be displayed. When the corresponding pin is given high,then particular LED glows.In a common anode arrangement, the common pin is given to a logic high and the pins of the LED are given low to display a number. In common cathode configuration, the negative terminals are connected to the common pins and the common is connected to the ground. These segments come in two outlines they are common cathode and common anode. In that 8 pins relate to the 8 LEDs, the remaining pins at middle are internally shorted. 7 segment Display Pin DiagramĪ seven segment displays are generally available in ten pin package. These segments are arranged in the form of 8 which is shown in the seven segment display circuit diagram. Seven segments are indicated as A-G and the eighth segment is indicated as H. This segment is useful while displaying non integer number. Actually seven segment displays contain about 8-segments wherein an extra 8th segment is used to display dot. These displays consist of seven segments of light emitting diodes (LEDs) and that is assembled into a structure like numeral 8. The seven segment display is the most common display device used in many gadgets, and electronic appliances like digital meters, digital clocks, microwave oven and electric stove, etc. Seven Segment Display Seven Segment Display
