"# QR"
This project demonstrates how to generate and display a QR code on an OLED screen using an Arduino board.
- Arduino board (e.g., Arduino Uno, Nano, etc.)
- OLED display (e.g., SSD1306)
- Connecting wires
Make sure you have the following libraries installed in your Arduino IDE:
- Adafruit SSD1306
- Adafruit GFX
- QR code generation library (
qrcode.h)
- Connect your OLED display to the Arduino board using the following pin configuration:
| OLED Pin | Arduino Pin |
|---|---|
| VCC | 5V |
| GND | GND |
| SDA | A4 (SDA) |
| SCL | A5 (SCL) |
-
Open the Arduino IDE and create a new sketch.
-
Copy and paste the following code into your sketch.
-
Upload the sketch to your Arduino board.
After uploading the sketch, the OLED display will show the generated QR code.
