Hello Dear Steemians, In this post of the i2c LCD i will provides two additional functions of scroll text From Right line and scroll in from Left (line to display text on, string to be scrolled). I will use STEEMIT PHILIPPINES our guild, to display on the LCD below.
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
void setup()
{
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.backlight();
lcd.setCursor(0,0);
lcd.print(" STEEMPH ");
}
void loop()
{
lcd.setCursor(16,1);
lcd.autoscroll(); // Set diplay to scroll automatically
lcd.print(" "); // set characters
delay(700);
}Here is the code that i made
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
const byte lcdAddr = 0x27; // Address of I2C backpack
const byte lcdCols = 16; // Number of character in a row
const byte lcdRows = 2; // Number of lines
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
// Demo parameters
const char demoText[]= " STEEMIT PHILIPPINES ";
const unsigned int scrollDelay = 500; // Miliseconds before scrolling next char
const unsigned int demoDelay = 2000; // Miliseconds between demo loops
byte textLen; // Number of visible characters in the text
void setup() {
textLen = sizeof(demoText) - 1;
lcd.begin(16, 2);
lcd.backlight();
lcd.print(demoText);
delay(demoDelay);
}
void loop() {
// Scroll entire text in a row to the left outside the screen
for (byte positionCounter = 0; positionCounter < textLen; positionCounter++) {
lcd.scrollDisplayLeft();
delay(scrollDelay);
}
// Scroll hidden text through entire row to the right outside the screen
for (byte positionCounter = 0; positionCounter < textLen + lcdCols; positionCounter++) {
lcd.scrollDisplayRight();
delay(scrollDelay);
}
// Scroll text to the right back to original position
for (byte positionCounter = 0; positionCounter < lcdCols; positionCounter++) {
lcd.scrollDisplayLeft();
delay(scrollDelay);
}
delay(demoDelay);
}I want to say Thank you to sir Terry
