Tutorial to Interface OLED 0.91inch 128x32 With Arduino UNO

This tutorial is going to teach you some basics on using OLED 0.91inch LCD128x32 with Arduino UNO

Step 1: Introduction

Description:

OLED 0.91 inch is a monochrome graphic display module with a built-in 0.91 inch, 128X32 high-resolution display. OLED 0.91inch is able to work despite the absence of backlight. In a dark environment, contrast of OLED display is higher than LCD display. This device is I^2C or SPI compatible. Due to its capability in displaying, it is often used in various application for instances, smart watch, MP3, function cellphone, portable health device and many others.

Specifications:

1. OLED display, no need backlight, self-illumination,

2. The display performance is better than the traditional LCD display, also lower consumption.

3. Driver IC: SSD1306

4. Size: 0.91 inch OLED

5. Resolution: 128 x 32

6. IIC interface

7. Display Color: white

8. Description:

GND: Power Ground

VCC: Power + (DC 3.3 ~5v)

SCL: Clock Line

SDA: Data Line

Step 2: Pin Definition

Step 3: Hardware Installation

Step 4: Sample Source Code

To get the result, please download the sample source code attached below.

*Kindly download the U8g2 library which is written for many types of LCD display.

Step 5: Include U8g2 Library

Click skecth and then click include library. Next, click add .Zip library and select the U8g2.zip file.

Step 6: Upload Source Code

Open the source code. Make sure com of arduino UNO and com port is same and please select the board is Arduino UNO.

Click upload.

Step 7: Result

Thank you so much for this, I'm using an RP2040 Pico and all examples I found use Micro-Python (I just don't get that). All I had to do was change the address of the display and it worked.
On the Pico the default SDA/SCL are GPIO 4 and 5
Thanks again.

For people without Winrar, you can also download this library in a zip from their Github, just click code> Download as Zip.

Excellent, thank you!

Does this module require external pullup resistors or they are already built in?
I want to use it with other MCU, not Arduino.

what made u pick that constructor vs say

U8G2_SSD1306_128X32_UNIVISION_1_SW_I2C(rotation, clock, data [, reset])

I have same-looking display, but my PINs r marked SCK/SDA.
My display (as yours as well) doesn't have reset pin @ all.
How did u know the buffer size to choose the constructor? A lucky guess?
What about Univision vs Winstar constructors?
