3 Develop an interfacing circuit and a sketch to display decimal data on 7-Segments. The 3- digit number is sent over serial communication.
Here i am using online IDE Tinkercad . If you don't know what is tinkercad then refer my blog HERE or else you can use offline IDE also.
Code:-
unsigned
const int A = 13;
unsigned
const int B = 12;
unsigned
const int C = 11;
unsigned
const int D = 10;
unsigned
const int E = 9;
unsigned
const int F = 8;
unsigned
const int G = 7;
unsigned
const int H = 6;

pinMode(D, OUTPUT);
pinMode(E, OUTPUT);
pinMode(F, OUTPUT);
