We successfully managed to display "Hello!" on our LCD screen, which is connected to the ESP32.
Here is the code:
#include <LiquidCrystal.h>
// Pin numbers for the LCD
const int rs = 15;
const int en = 13;
const int d4 = 32;
const int d5 = 33;
const int d6 = 25;
const int d7 = 26;
// Create a LiquidCrystal object
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
void setup() {
// Initializing the LCD with its number of columns and rows, knowing ours is a 0802A
lcd.begin(8, 2);
}
void loop() {
lcd.clear(); // Clear the LCD
lcd.print("Hello!"); // Print a message
delay(1000); // Wait for a second
}
These are our wirings:
And this is the display:
