I bought this on the store near us. Here is the PDF for it.


I followed the instructions below and uploaded the code and all I've got is this Uploaded

I've reconnected it and used a different jumper wires, still the same result.

#include <LiquidCrystal.h>

LiquidCrystal lcd(12,11,5,4,3,2);

void setup(){

void loop(){

    How did you wire the LCD to your Arduino? Which model of Arduino are you using? – Duncan C Oct 20 '19 at 20:23
  • Exactly as like with the pdf. I'm using arduino uno, I never had issues with my microcontroller and the code seems to compile and get uploaded to the board seemingly. I've tried to change the pins on the code and on the actual it still does not work. – MIGGYEE Oct 22 '19 at 8:07
  • The PDF shows 2 different ways of connecting the display to the Arduino. Which method are you using? – Duncan C Oct 22 '19 at 12:05
  • I tried both and it's the same output. – MIGGYEE Oct 23 '19 at 13:32
  • I guess no one knows. – MIGGYEE Oct 27 '19 at 6:04
