I'm having a strange problem with my lcd display where the demo code works perfectly but my code results in a corrupt screen with the same settings. This demo code works correctly
// include the library code:
#include <LiquidCrystal.h>
// initialize the library by associating any needed LCD interface pin
// with the arduino pin number it is connected to
const int rs = 12, en = 11, d4 = 10, d5 = 4, d6 = 1, d7 = 0;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
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);
}
but my code results in garbage on the display. Would the pins I'm using in my code be conflicting with the serial monitor, hence the problem? The serial monitor is working ok, I'm using a Nano v3.1 if it's relevant.
