  First watch this full video. only then. Start making this project.  //Arduino Code// #include <LiquidCrystal.h> char str [ 34 ], L = 2 ; int draft = 0 , i = 0 ; int Pass = 0 , p = 0 ; int c , x , d ; LiquidCrystal lcd ( 11 , 10 , 5 , 4 , 3 , 2 ); void setup () { Serial . begin ( 9600 ); pinMode ( 7 , OUTPUT ); lcd . begin ( 16 , 2 ); } void loop () { if ( draft == 1 ) { check (); draft = 0 ; i = 0 ; delay ( 1000 ); } } void serialEvent () { while ( Serial . available ()) { char inChar = Serial . read (); str [ i ++ ] = inChar ; delay ( 10 ); } for ( p = i + 1 ; p < 34 ; p ++ ) { str [ i ++ ] = 32 ; } draft = 1 ; Serial . write ( str ); lcd . setCursor ( 0 , 0 ); lcd . print ( str ); if ( i > 16 ) { d = 16 ; for ( x = 0 ; x <= 17 ; x ++ ) { lcd . setCursor ( x , 2 );...
