Hey guys.. Im having some trouble uploading this code.. which I will post down below. Its about a morse code translator. You type in the words in the serial monitor...https://www.instructables.com/id/Learning-Morse/ ..here is the link
#include <Wire.h> //libraries of the LCD with I2C

#define LED_OFF 0
#define LED_ON 1

int ledPin = 8;
char* letters[] = {
".-", "-...", "-.-.", "-..", ".", "..-.", "--.", "....", "..", // letters A-I
