Topic: Arduino Printing to LCD from Serial Port (Read 540 times) previous topic - next topic


Help Please,
I am trying to get my Arduino to print out on an LCD screen attached to the Arduino but all it is doing is printing to the serial port. I want to be able to enter something in the serial port text box and have it print onto the LCD screen?


Hello and welcome :)

Show your code and we might be able to help :)


Sorry I forgot some of my code...

#include <LiquidCrystal.h>

LiquidCrystal lcd(8, 9, 4, 5, 6, 7);

void setup() {
    lcd.begin(16, 2);
    lcd.setCursor(0, 0);


void loop(){

  //set text alignment to left as default
        if( alignLEFT ) {
     if (!hideTop) lcd.print("Date");
     lcd.setCursor(0, 1);
     if (!hideBot) lcd.print("Nov. 19th");
         //set text alignment to the right       
        if( alignRIGHT ){
     if (!hideTop) lcd.print("            Date");
            lcd.setCursor(0, 1);
     if (!hideBot)lcd.print("       Nov. 19th");
        lcd.setCursor(0, 0);


Where are alignLEFT, alignRIGHT, hideTop and hideBot defined or updated?
