💡 Note: Some boards (like Arduino Mega, ESP32) may have different I2C pin assignments.
Caution:
🔹 If the screen appears blank with a blue or green background, the contrast might need adjustment.
🔹 Gently turn the trimpot knob (small blue square on the I2C module) using a screwdriver to adjust the display visibility.
🔹 Do not force the trimpot, as excessive pressure may damage it.
