Sevensegment displays are an arrangement of LEDs that simply accept a digital input to display a digit from 0 to 9. Depending on which number or alphabet is to be displayed, control signals are applied. To set the 7-Segment LED with binary code, you have to write the code sequence from a-g and left to right with start with binary

Forexample, to display ‘5’ on the 7-segment, the LEDs that should be illuminated are ‘a’, ‘c’, ‘d’, ‘f’ and ‘g’. So, the port pins should give the output 0b10010010 to the 7-segment, which is equivalent in hex to 0x92. The inner ‘for’ loop displays the ones counter and the outer ‘for’ loop is for the tens counter.

Thedisplay consists of seven segments identified by a letter (from a to g ), organized as follows: and each segment is generally associated with an LCD screen or a LED and Aseven-segment display (SSD) is a form of electronic display device for displaying decimal numbers. They can be used as an alternative to complex display's such as dot matrix.
