6 FISRT OLED CODE HELLO WORLD

 /*

 * WELCOME TO C++ PROGRAMMING - GRADE 6

 * This is your first program! We will print a name on the OLED screen.

 */

// 1. LIBRARIES ( The Tools )

// We include special "books" of code that teach the ESP32 how to use the screen.

#include <Wire.h>

#include <Adafruit_GFX.h>

#include <Adafruit_SSD1306.h>

// 2. SCREEN CONFIGURATION ( The Hardware )

// We tell the ESP32 the size of our screen (128 pixels wide, 64 pixels tall).

#define SCREEN_WIDTH 128

#define SCREEN_HEIGHT 64

// We create a "control object" for the screen. Think of this as the remote control.

Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);

// 3. YOUR VARIABLES ( The Data )

// **********************************************************

// STUDENT: CHANGE THE TEXT INSIDE THE QUOTES BELOW!

// **********************************************************

String name_here = "MARIE CURIE";

void setup() {

  // This part runs ONLY ONE TIME when you turn on the ESP32.

 

  // A. Start the connection to the screen

  // (0x3C is the address/ID of the screen)

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

    // If the screen is not found, stop here.

    for(;;);

  }

  // B. Clean the screen (erase old drawings)

  display.clearDisplay();

  // C. Set up the text style

  display.setTextSize(2);      // Size of the text (1 is small, 2 is medium)

  display.setTextColor(WHITE); // Color of the text (OLEDs are usually only one color)

 

  // D. Choose where to start writing (Column 10, Row 20)

  display.setCursor(10, 20);

  // E. Print the variable we created above

  display.println(name_here);

  // F. IMPORTANT: Push the information to the screen!

  // Nothing appears until we use this command.

  display.display();

}

void loop() {

  // This part repeats forever.

  // Since we only want to show the name once, we leave this empty!

  // Relax, ESP32!
