Tutorial: How to use Pro ESP32 OLED V2.0

The Pro ESP32 OLED V2.0 is a small graphic display ideal for ESP32-based projects. Useful for beginners and intermediates.

What you need

• ESP32
• Arduino IDE
• FTDI cable
• Pro ESP32 OLED V2.0
• 10kΩ resistor
• Micro USB

Steps

1. Check the datasheet for your ESP32 specifications.
2. Download and install the Arduino IDE.
3. Connect the Pro ESP32 OLED V2.0 to your ESP32 via the pins defined in the datasheet.
4. Connect to your ESP32 with a Micro USB cable.
5. Install the Adafruit_SSD1306 library via the Arduino Library Manager.
6. Create a new sketch in your Arduino IDE.
7. Insert the following code to initialize and display text on the screen:
8. “`cpp
   #include
   #include

   #define SCREEN_WIDTH 128
   #define SCREEN_HEIGHT 64

   Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire);

   void setup() {
   display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
   display.clearDisplay();
   display.setTextSize(1);
   display.setTextColor(SSD1306_WHITE);
   display.setCursor(0, 0);
   display.print(“Welcome!”);
   display.display();
   }

   void loop() {}
   “`

9. Load the sketch onto your ESP32.

Example code

```cpp
#include <Wire.h>
#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128
#define SCREEN_HEIGHT 64

Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire);

void setup() {
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  display.clearDisplay();
  display.setTextSize(1);
  display.setTextColor(SSD1306_WHITE);
  display.setCursor(0, 0);
  display.print("Benvenuto!");
  display.display();
}

void loop() {}
```

Mini project

Create a simple stopwatch that displays the time on the OLED display.
