HELP!- Arduino Micro don't work with OLED 0.96'' Why?

Other Hardware Displays

Hi to everyone! (Sorry for my english, greets from Argentina to you :smiley: )

Im new in this website, in my Arduino project im trying to show something in an OLED 0.96'', but i can't find a code that permits me work with it, y have an Arduino Pro Micro, can someone help me with this?

PICTURES ARE ATTATCHED TO THE POST (link of imagur)

#include <SPI.h>

THE CODE IS MORE LARGE BUT I CAN'T UPLOAD MORE THAN 9000 CHARACTERS

Try running this sketch with the display connected, if it detects anything you know you have connected the display correctly (as long as no other device is on the I2C bus)

// I2C Scanner
// Written by Nick Gammon
// Date: 20th April 2011

#include <Wire.h>

void setup() {
  Serial.begin (9600);

  // Leonardo: wait for serial port to connect
  while (!Serial) 
    {
    }

  Serial.println ();
  Serial.println ("I2C scanner. Scanning ...");
  byte count = 0;
  
  Wire.begin();
  for (byte i = 8; i < 120; i++)
  {
    Wire.beginTransmission (i);
    if (Wire.endTransmission () == 0)
      {
      Serial.print ("Found address: ");
      Serial.print (i, DEC);
      Serial.print (" (0x");
      Serial.print (i, HEX);
      Serial.println (")");
      count++;
      delay (1);  // maybe unneeded?
      } // end of good response
  } // end of for loop
  Serial.println ("Done.");
  Serial.print ("Found ");
  Serial.print (count, DEC);
  Serial.println (" device(s).");
}  // end of setup

void loop() {}

Starting code of CrazyVito1. - Album on Imgur I've do it and the red led's of the arduino had blinked, then i've tryied with the code of the OLED and nothing goes on working on the screen nor nothing appears on it.

you are using the adafruit lib?
Have you corrected the files and run the included sketches?

have you connected it correct?
need photo of your connections.

btw search for arduino throttle as i have just spent the whole weekend wrestling with one and got it to work.

The code doesn't display anything on the display, it only scans the I2C bus for devices.
You need to run the code with the serial monitor open, it shows the devices it found there (unless you connected it wrong).

I first just want to make sure the display is available on the bus before we try anything else, so run the code and post what it says inside the serial monitor

Is there a similar sketch to check SPI devices?
