How to interface OLED Display with Arduino Step by Step

Step-by-Step Tutorial: How to Interface OLED Display with Arduino

1. Introduction

• Watch the video titled "How to interface OLED Display with Arduino Step by Step" from the channel Tech Maker for a visual guide.

2. Subscribe and Prepare Materials

• Click on the subscribe button and hit the bell icon on the Tech Maker channel to get notified of new videos.
• Gather the necessary materials:
  • OLED Display (128x64 pixels)
  • Arduino board
  • Breadboard
  • Jumper wires
  • USB cable for Arduino

3. Physical Connection

• Insert the OLED display carefully onto the breadboard.
• Connect the components as follows:
  • Ground of OLED display to the ground of Arduino.
  • VCC of OLED display to the 5V pin of Arduino.
  • SCL pin of OLED display to the A5 pin of Arduino.
  • SDA pin of OLED display to the A4 pin of Arduino.

4. Code Setup

• Download and install the necessary libraries:
  • Adafruit SSD1306 library
  • Adafruit GFX library
• To add the libraries, go to Sketch -> Include Library -> Add .ZIP Library.
• Download the libraries from the provided link in the video description.

5. Library Configuration

• Modify the Adafruit SSD1306 library:
  • Go to the library location in Arduino IDE.
  • Open the Adafruit_SSD1306.h header file.
  • Uncomment the line for 128x64 display and comment the line for 128x32 display.
  • Save the file and close it.

6. Upload the Code

• Connect your Arduino board to your computer using the USB cable.
• Upload the code provided in the video to your Arduino board.

7. Display Output

• After uploading the code, you should see "Hello World" printed on the OLED display.
• The code initializes the display, sets font size, color, cursor position, and displays text accordingly.

8. Final Steps

• Verify that the OLED display is functioning correctly with the Arduino.
• Experiment with different text, fonts, and colors to customize the display output.
• You have successfully interfaced an OLED display with Arduino!

9. Conclusion

• You have completed the tutorial on interfacing an OLED display with Arduino.
• For more projects and tutorials, stay tuned for the next video from Tech Maker.

By following these steps, you should be able to successfully interface an OLED display with an Arduino board.
