FAQ:

• What library do I install? Z
  Arduino IDE → Sketch → Include Library → Manage Libraries → search “LiquidCrystal I2C” → install Frank de Brabander version. Done!
• Why is my screen blank?
  Turn the blue screw-pot clockwise 3 full turns. If still blank, run I2C scanner code to confirm address (usually 0x27).
• Can I change the I2C address?
  Yes – solder any A0/A1/A2 pads on the back to GND. Each soldered pad adds +1 to address (0x20 to 0x27).
• Will it work with ESP32?
  100%. Connect SDA→21, SCL→22, VCC→5V, GND→GND. Use same library.
• How to turn backlight off?
  Remove the jumper cap next to the pot. Re-insert to turn ON again.
• Can I display Bangla/Arabic?
  Yes – create custom characters (8 slots) using lcd.createChar() and print them.
• Is the backlight PWM dimmable?
  Hardware jumper only (ON/OFF). For PWM dimming, cut jumper and control via transistor/MOSFET from MCU pin.
• What is the viewing angle?
  6 o’clock direction (best from below). For top-view, order yellow-green version.
• Does it come with header pins soldered?
  Yes – straight male headers ready for breadboard. Female-female jumper cable included.
• How to scroll text?
  lcd.setCursor(0,0); lcd.print(” >>> SCROLLING TEXT DEMO <<< “); for(int i=0;i<15;i++){ lcd.scrollDisplayLeft(); delay(400); }
