Cómo programar y conectar el Display Oled de 0.96 con Arduino Uno

En el siguiente tutorial aprenderás como conectar el Display Oled de 128×64 0.96 a un Arduino Uno y programarlo para mostrar imágenes y textos. Los materiales a utilizar son los siguientes:

¿Display Oled 128×64 SSD1306 como utilizar con Arduino UNO?

Para utilizar el Display Lcd Oled 128×64 de 0.96 pulgadas con la tarjeta de desarrollo Arduino Uno puedes realizar dos tipos de conexiones se muestran en las siguientes imágenes:
  • 3.3V del Arduino Uno conectar al pin Vcc del Oled
  • GND del Arduino UNO conectar al pin GND del Oled
  • Pin A4 del Arduino Uno conectar al pin SCL del Oled
  • Pin A5 del Arduino Uno conectar al pin SDA del Oled

1- Primera conexión:

Conexion_GPS_NEO6_Arduino_Uno

2- Segunda conexión:

Conexion_GPS_NEO6_Arduino_Uno
En las dos imágenes se demuestran las conexiones que debes de hacer con tu Arduino Uno y tu Oled, te preguntaras por que es posible que funcione con estas 2 tipos de conexiones y es por que esos pines están reservados para que realices una comunicación con SCL y SDA. Si es tu caso y no estas utilizando Arduino Uno solo busca el pinout de la placa que estés utilizando y identifica los pines reservados SCL y SDA y ahí conecta tu Display Oled.

Cuando realices las conexiones de tu Arduino Uno y el Oled abre el IDE de Arduino he importa las librerias de Adafruit GFX graphics y Adafruit_SSD1306, ya que incluiste las librerías tienes que realizar un cambio a la librería Adafruit_SSD1306, solo tienes que buscar la carpeta “libraries” de donde se instalo tu arduino, posterior mente buscar la carpeta de “Adafruit_SSD1306-master” y abrir el archivo “Adafruit_SSD1306.h” con cualquier editor de código, te recomendamos Notepad++, busca la linea de código numero 29 y coméntala agregando al principio dos // y descomenta la linea 28, borrando las //. Después debes guardar y cerrar el editor de texto. En la siguiente imagen se muestra como hacerlo:
Editar la librería Adafruit_SSD1306

Por ultimo te comparto este código para que lo puedas probar en tu Oled y verificar su funcionamiento:

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