[RadioDJ]

Ser direkt 2 fel.
Du har dubbla void setup() och dubbla void loop().

Börja med att ta bort dessa 2 som finns längst ner i din kod.
De är ändå tomma och gör inget.

Det går inte att ha mer än en av varje.

[slft]

här ser du hur man gjort på ett annat ställe
lite mer lättläst

och jag är ingen programerare!

#include <LiquidCrystal_I2C.h> // F Malpartida's NewLiquidCrystal library


#define I2C_ADDR 0x20 // Define I2C Address for controller
#define BACKLIGHT_PIN 7
#define En_pin 4
#define Rw_pin 5
#define Rs_pin 6
#define D4_pin 0

[kodar-holger]

Lägg den kod som skall köras om och om igen i loop istället för i setup. Det är det dom är till för.

Kod: Markera allt

void setup()
{
//Koden här körs en gång
}

void loop()
{

Lämna kvar de första radern fram till ...backlight() i setup() och klipp och klistra resten till loop(). Antar att både setup() och loop() är nåt Arduino mer eller mindre kräver, eftersom de finns färdigt i en "tom" sketch.

Om du lär dig lite rudimentär C så kanske det går bättre.

[nifelheim]

du har kommenterat bort setup

//void setup()


kolla vad kodar-holger skrev,
du ska inte ha loop() inne i setup()

  lcd.backlight();
}

void loop()
{
  //börja loopen med tom display
  lcd.init();  // kanske fungerar med lcd.clear(); här istället, ifall det finns i det använda biblioteket
  // Print a message to the LCD.
