OLED Display 0.96" I2C IIC Blue

OLED Display 0.96 inch Blue color, compatible with Arduino and other development boards. Ideal for small size projects due to the I2C and IIC communication interface.

This display does not require backlighting (it is provided by the pixels)

High resolution: 128X64

Viewing angle: >160 °

Ultra low power consumption: 0.08W

Power supply voltage: DC 3V-5V

Operating temperature: -30 ~70 degree

Dimensions mm: 29 x 27.5 x 4.3

Active display dimensions mm: 26.5 x 14.8

Support: IIC, I2C

Direct I/O level compatibility with 3.3V and 5V microcontrollers (directly compatible, no converters needed)

Chip: SSD1306

IIC communication uses a minimal number of pins.

Test code:

#include // Include core graphics library for the display

#include // Include Adafruit_SSD1306 library to drive the display

Adafruit_SSD1306 display(128, 64); // Create display

#include // Add a custom font

#include // Add a custom font

int Variable1; // Create a variable to have something dynamic to show on the display

void setup() // Start of setup

{

delay(100); // This delay is needed to let the display initialize

display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // Initialize display with the I2C address of 0x3C

display.clearDisplay(); // Clear the buffer

display.setTextColor(WHITE); // Set color of the text

display.setRotation(0); // Set orientation. Options are 0, 1, 2 or 3

display.setTextWrap(false); // By default, long lines of text automatically “wrap” back to the leftmost column.

// To override this behavior (so text will run off the right side of the display - useful for

// scrolling marquee effects), use setTextWrap(false). The normal wrapping behavior is restored

// with setTextWrap(true).

display.dim(0); // Set brightness (0 is maximum and 1 is a little dim)

} // End of setup

void loop() // Start of loop

{

Variable1++; // Increase variable by 1

if(Variable1 > 150) // If Variable1 is greater than 150

{

Variable1 = 0; // Set Variable1 to 0

}

// Convert Variable1 into a string, so we can change the text alignment to the right:

// It can also be used to add or remove decimal numbers.

char string[10]; // Create a character array of 10 characters

// Convert float to a string:

dtostrf(Variable1, 3, 0, string); // (, , , )

display.clearDisplay(); // Clear the display so we can refresh

display.setFont(&FreeMono9pt7b); // Set a custom font

display.setTextSize(0); // Set text size. We are using a custom font so you should always use the text size of 0

// Print text:

display.setCursor(0, 10); // (x,y)

display.println("Hello"); // Text or value to print

// Draw triangle:

display.drawTriangle(40,40, 50,20, 60,40, WHITE); // Draw triangle. X, Y coordinates for three corner points defining the triangle, followed by a color

// Draw filled triangle:

display.fillTriangle(0,63, 15,45, 30,63, WHITE); // Draw filled triangle. X, Y coordinates for three corner points defining the triangle, followed by a color

// Draw line:

display.drawLine(40, 63, 70, 63, WHITE); // Draw line (x0,y0,x1,y1,color)

// Draw circle:

display.drawCircle(47, 36, 20, WHITE); // Draw circle (x,y,radius,color). X and Y are the coordinates for the center point

// Draw a filled circle:

display.fillCircle(12, 27, 10, WHITE); // Draw filled circle (x,y,radius,color). X and Y are the coordinates for the center point

// Draw rounded rectangle and fill:

display.fillRoundRect(58, 0, 18, 18, 5, WHITE); // Draw filled rounded rectangle (x,y,width,height,color)

// It draws from the location to down-right

// Draw rectangle:

display.drawRect(79, 0, 49, 27, WHITE); // Draw rectangle (x,y,width,height,color)

// It draws from the location to down-right

display.setFont(&FreeMonoBold12pt7b); // Set a custom font

// Print variable with left alignment:

display.setCursor(83, 20); // (x,y)

display.println(Variable1); // Text or value to print

// Draw rounded rectangle:

display.drawRoundRect(79, 37, 49, 27, 8, WHITE); // Draw rounded rectangle (x,y,width,height,radius,color)

// It draws from the location to down-right

// Print variable with right alignment:

display.setCursor(83, 57); // (x,y)

display.println(string); // Text or value to print

display.display(); // Print everything we set previously

} // End of loop
