ESP32 Lyrics

This project uses an ESP32 to control an OLED display. The display shows words sequentially with specified delays.

Requirements

Materials	Quantity
ESP32	1
OLED Display (0.96 in, 128x64, IIC)	1
Breadboard	1
LED (soon)	3
M-F Jumper Wires	4

Programming
I used the Arduino IDE with the ESP32 library.

Install the IDE from its official website
Also install the required library inside Arduino IDE:
Wire (included in Arduino Libary)
Adafruit GFX Library
Adafruit SSD1306
ESP32 Board Manager for Arduino:
https://dl.espressif.com/dl/package_esp32_index.json

Source Code

#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 64
#define OLED_RESET    -1

Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

// modify the lyrics here --
String words[] = {"Labis", "na", "naiinip", "Nayayamot", "sa", "bawa't", "saglit"};
// modify the delay here --
int wordDelays[] = {500, 400, 1400, 1400, 300, 600, 1000};

void setup() {
  Serial.begin(115200);

  if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {
    for (;;);
  }

  display.clearDisplay();
}

void loop() {
  for (int i = 0; i < sizeof(words) / sizeof(words[0]); i++) {
    display.clearDisplay();
    display.setTextSize(2);
    display.setTextColor(SSD1306_WHITE);
    display.setCursor(0, 20);
    display.println(words[i]);
    display.display();
    delay(wordDelays[i]);
  }
}

Take note that this code will loop.
