![]() ![]() We can refer each line/segment "a,b,c,d,e,f,g" and for dot character we will use "h". We can refer each segment as a LINE, as we can see there are 7 lines in the unit, which are used to display a number/character. It just consists 8 LEDs, each LED used to illuminate one segment of unit and the 8 th LED used to illuminate DOT in 7 segment display. It’s the simplest unit to display numbers and characters. We are using AT89S52 microcontroller from 8051 series.īefore interfacing, we should learn about 7 segment display. In this tutorial, we are going to learn how to interface a 7 segment display with 8051 microcontroller. ![]() ![]() It can also display some character alphabets like A,B,C,H,F,E etc. Seven segment displays are important display units in Electronics and widely used to display numbers from 0 to 9. ![]()
