Hello World on OLED Display Using Arduino
This project demonstrates how to use an Arduino to display a "Hello, world!" message on an OLED display.
By interfacing the SSD1306 OLED display with the Arduino and using the Adafruit_GFX and Adafruit_SSD1306 libraries, you can easily display text and graphics on the screen.
Components Needed
- Arduino UNO
- 128x64 OLED Display
- Jumper Wires
- Breadboard
Block Diagram
Hardware Wiring Explanation:
Connect the OLED Display to Arduino:
Connect the VCC pin of the OLED display to 5V (or 3.3V, depending on your OLED display) on the Arduino.
Connect the GND pin of the OLED display to GND on the Arduino.
Connect the SDA (Data) pin of the OLED display to analog pin A4 on the Arduino.
Connect the SCL (Clock) pin of the OLED display to analog pin A5 on the Arduino.
Power the Arduino
Connect the Arduino to your computer using a USB cable.
Software (Arduino IDE):
Open the Arduino IDE on your computer.
Write or paste the provided program into the IDE.
Select the correct board and port in the Arduino IDE under the Tools menu.
Upload the program to the Arduino.
The OLED display will show a heart shape at specified coordinates.
Below the heart shape, the text "Hello, world!" will be displayed.
Project Operation
Serial communication is initiated at a baud rate of 115200.
The SSD1306 OLED display is initialized with the I2C address 0x3C.
If the display fails to initialize, an error message is printed to the Serial Monitor.
Displaying the Heart and Text:
The display is cleared to ensure no residual graphics are shown.
The
Text size is set to 1, and text color is set to white.
The cursor is positioned, and the text "Hello, world!" is printed to the display.
The
