| Display Not Found | Run I2C scanner sketch, check SDA/SCL connections |
| Partial/Cut Display | Wrong driver (SH1106 vs SSD1306), adjust library settings |
| Flickering | Use display.clearDisplay() before updates, check power supply |
| Dim Display | OLED aging, adjust contrast: display.dim(true) or .dim(false) |
| Ghosting/Burn-in | Permanent from static images, prevent with varied content |
| Text Garbled | Verify 128×64 resolution in code, not 128×32 |
| I2C Error | Add pull-up resistors (4.7kΩ) to SDA/SCL if long wires |
💡 Pro Tips

⚠️ Important: Requires Adafruit_SSD1306 + Adafruit_GFX libraries (or U8g2). Arduino Uno: SDA=A4, SCL=A5. Initialize: display.begin(SSD1306_SWITCHCAPVCC, 0x3C). Must call display.display() to update screen (buffered output). Text capacity: Size 1 = 21 chars × 8 lines, Size 2 = 10 chars × 4 lines. Graphics capable: full bitmap support, shapes, animations. OLED lifespan: ~10,000-20,000 hours – avoid static images to prevent burn-in. Blue OLEDs may dim faster than white versions. Power depends on lit pixels (black=off, blue=on). Works with 3.3V or 5V supply. Some modules use SH1106 driver instead of SSD1306 – try U8g2 library if Adafruit doesn’t work. Perfect for: Arduino projects, ESP32/ESP8266 IoT, wearables, sensor displays, menus, portable devices. Not suitable for: Full-color needs, high-speed video, permanent static displays. Best size/resolution balance for most projects!
