I know this has already been discussed a few times, but it's sort of different for me: I want to simulate my game on Tinkercad before I build it, but the 16x2 LCD I am using for my game half the time shows the ç (cedilla) symbol before each word. And the lcd.clear() does not always clear the words. To be clear, this is all on Tinkercad.
The following is the code for my whole game:
#define NOTE_C3 131
#define NOTE_C4 262
#define NOTE_G3 196
#define NOTE_A3 220
#define NOTE_B3 247
#define NOTE_B0 31
#define NOTE_D3 147
//Defining notes for piezo (used later on)
#include <LiquidCrystal.h>
//add LCD library to be able to print on the LCD
LiquidCrystal lcd(0,15,16,17,18,19);
//initialize the LCD
String array[] = {"Welcome!", "To this game", "This is a Simon", "Says Game!",
"In This Game,", "You Have To See", "The Pattern of",
"The LEDs in a","row of 6 blinks", "and then copy",
"them exactly", "with the buttons", "underneath them.",
"Just like a", "Simon Says Game", "There are a",
"Total of 20", "levels, and each", "level is harder",
"than the last.","You have a max", "of 5 tries.",
"Try your best!"};
//creates array of words for instructions at beginning of game
int startBut = 1; //pin number of start Button
int buz = A0; // pin number of piezo
int maxLevel = 6; // number of LED blinks in one level
int ledSeq[6]; // sequence of the LEDs
int mySeq[6]; // sequence that the player enters
int speed = 1000; // initial speed of LED blinks
int gameTimes = 0; // initial number of game errors
int level = 1; // initial level that player starts with
int points = 0;// initial points that player starts with
int lcdHelp = 0;// variable used to print out every 2nd string in LCD array
int melody[] = {
NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, 0, NOTE_B3, NOTE_C4
};
// tune for game when player wins a level/the game
int noteDurations[] = {
4, 8, 8, 4, 4, 4, 4, 4
};

I mainly start having an issue in the butPres() method, specifically when the word BEGIN is displayed, there is a ç before it. And afterwards, when lcd.clear() is supposed to clear BEGIN, it just stays on the display. And later, when I press the wrong button, and the incorrectSeq() method is implemented, the words WRONG ORDER are printed after the button, even though there is a lcd.clear() before it.
The following is a video showing my problem:
This is my first time posting, and I am an extreme beginner at coding, so I'm sorry in advance if most of my code is redundant or doesn't make sense. Thank you for the help!
