Arduino type: mega 2560
LCD type: TFT LCD Mega shield V1.2
After connecting pc and arduino ligth of LCD is on but when we try to execute the following code we cant see anything on the LCD screen. We are new at this and try to learn. Thats why we cant understand reasons of problems. What can cause this problem ?
We think maybe we write wrong pin number on code..
code as follow:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("hello, world!");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
}
