ESP32-OLED

ESP32-OLED

Aim:

This experiment shows how to display the message on OLED using ESP32-Microcontroller.

Description:

To display message on OLED screen. 

Hardware required:

ESP32-Microcontroller Development board

Pin connection:

Pin Mapping:

OLED	ESP32
5V	5V
SCL	IO22
SDA	IO21

Procedure:

1.        The above pin connection shows how to interface OLED with ESP32 board.

2.        Do the connections as shown in the pin diagram and pin mapping.

3.        Connect the USB cable to the board.

4.        Open Arduino IDE .Select DOIT ESP32 DEVKIT V1in boards and select COM port.

5.        Verify the program and Upload it.

6.    Now you can see the output displaying the message on OLED of ESP32 microcontroller board.

Program:

#include<Wire.h> #include"SSD1306.h"

/* SDA=21,SCL=22 */

SSD1306 display(0x3c,21,22); void setup(void)

{

display.init();

/* display message in OLED */ display.drawString(0,0,"RDL Technologies PVT. LTD."); display.display();

}

void loop(void)

{

}

Output:
