Design with Adafruit OLED Color 0.96 inch 96x64 w microSD in Cirkit DesignerThe Adafruit OLED Color 0.96 inch 96x64 with microSD is a compact and vibrant display module suitable for adding visual output to your electronics projects. This OLED (Organic Light Emitting Diode) display boasts a 96x64 pixel resolution with full-color capabilities, making it ideal for displaying graphics, images, and custom user interfaces. The inclusion of a microSD card slot allows for expanded storage options, enabling the display of images and data files directly from a microSD card.
This circuit consists of an Arduino 101 microcontroller connected to a 0.96" OLED display via I2C communication. The Arduino runs a program that initializes the OLED and continuously displays an animated sequence of frames on the screen.

#include <Adafruit_GFX.h> // Include core graphics library for the display
#include <Adafruit_SSD1331.h> // Include the OLED driver library
// Pin definitions for the Arduino UNO

// Create an Adafruit_SSD1331 object
Adafruit_SSD1331 display = Adafruit_SSD1331(cs, dc, mosi, sclk, rst);
void setup() {
display.begin(); // Initialize the display
display.fillScreen(BLACK); // Clear the screen to black
}
void loop() {
// Example: Draw a red rectangle
display.drawRect(10, 10, 50, 40, RED);
delay(500);
// Example: Fill the rectangle with blue color
display.fillRect(10, 10, 50, 40, BLUE);
delay(500);
}
Note: This example assumes that the display is connected in SPI mode. Make sure to install the Adafruit GFX and SSD1331 libraries before uploading the code to your Arduino UNO.
Q: Can I power the display with 5V? A: Yes, the display can be powered with a 5V supply, but the logic level for data pins is 3.3V.
Q: How do I store images on the microSD card for the display? A: Images should be stored in a compatible format (e.g., BMP) and the card should be formatted to FAT16 or FAT32.
Q: Can I use this display with other microcontrollers besides Arduino UNO? A: Yes, the display can be used with any microcontroller that supports SPI or I2C communication, provided you adapt the pin connections and logic levels accordingly.
