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); }
