Simple Digital Clock with Big Font on 16x2 LCD Using Arduino in Bangla
Hello Friends, In This Blog, I will show you How to Make a Simple Digital Clock with Big Font on a 16x2 LCD Using Arduino in Bangla. This project is suitable for School, college & university projects. I am using Arduino Uno & 16x2 LCD display. There was a new thing which is the BIG font on a 16x2 LCD Display.
Full Code:
// include the library
#include <LiquidCrystal.h>
// initialize the interface pins
LiquidCrystal lcd(2,3,4,5,6,7);
int s,m,h,a,d,state,state1,state2,dg,cnt;
// the 8 arrays that form each segment of the custom numbers
