LCD hello world

im having a problem I bought a kit from here:

Using the Hello World example , following the diagram from here.

basically its just blinking a cursor, no text display

here's a video sorry for the background sound

What LCD do you have? What problem are you having?

sorry added the info

That’s certainly a rat’s nest of wires. It’s why I like my serial LCD so much. Just three wires.

You are allowed to use multiple color wires, you know.

Anyway, I’d suspect a wiring issue. Or a mismatch between the pins used and the code.

What does your code look like?

the code is just the default helloworld

// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
  // set up the LCD's number of rows and columns: 
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("hello, world!");

void loop() {
  // set the cursor to column 0, line 1
  // (note: line 1 is the second row, since counting begins with 0):
  lcd.setCursor(0, 1);
  // print the number of seconds since reset:

You are allowed to use multiple color wires, you know.

yea but that cost's more

the LCD part # is QY-1062A if that helps

Make life easy on yourself and solder the LCD to header pins and plug it into the board. These things are tricky enough if your wiring is good, and yours is a mess.

A model LCD circuit :

the code is just the default helloworld

There's a lot to be learned about the problem from seeing the code. The most obvious is that you are using the LiquidCrystal library, and that you need to have 6 data pins correctly connected.

You also need, of course, to have power and ground connected, and may need (or want) to provide power for a backlight.

pluggy provided a great picture of how the LCD should be connected, although that setup does not match the pin values you are using. So, if you go that route (recommended as you can see that it works), you'll need to change the LiquidCrystal instance's pins.

I ended up soldering the header pins last night to it but didn't have time to re-post, i go back on Tuesday and ill take some more pics, i kinda cleaned up the wires , just hard because they're the precut ones
