A better way to display large texts in your arduino uno 16 x 2 display without using the display scroll function
// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int okay=0;
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
delay(1000);
}
void myprintfunc(String s)
{
//printing forwards
int l=s.length();
for(int i=0;i<l-15;i++)
{
lcd.clear();
lcd.print(s.substring(i,i+16));
delay(500);
}
//printing backwards
delay(2000);
//delay of 2 sec before going back
for(int i=l-1;i>=16;i--)
{
lcd.clear();
lcd.print(s.substring(i,i-16));
delay(350);
}
}
void loop() {
myprintfunc("This is a test to check and test and see how this function handles large strings.");
delay(1000);
//Delay of 1 sec before retarting the loop
