LCD-Display showing phrase according to bluetooth input

Other Hardware Displays
1

Hello,

Iam trying to build wireless device which is connected to an lcd display. The displayis supposed to view a set Phrase depending on the number ur sending via bluetooth.

For example i want to send a "1" from the bluetooth terminal and then the arduino should display a phrase according to the set parameter "1". I want to make a list with a couple of phrases and the Number "0" is supposed to shut off the Display.

here is the code i've started with:

char Daten;

#include <LiquidCrystal_I2C.h>;

LiquidCrystal_I2C lcd(0x27, 16, 2);

void setup() {

lcd.init();

lcd.backlight();

Serial.begin(9600);

}

void loop() {

if(serial.available())

{

[Daten=Serial.read](https://daten%3Dserial.read/)();

}

If (Daten=='1')

{

lcd.setCursor(0, 0);

lcd.print("10% Rabatt")

}

If (Daten=='0')

{

lcd.setCursor(0, 0);

lcd.print("")

}

}

A short sketch of the circuit would be highly appreciated too.

I really do appreciate ur patience.

Thanks in advance!!

Hi
Your code is correct;
But there are some ";" missing which will cause compilation error.

and Serial. must be capital "S" if (serial.available())
IF use if If (Daten == '1')
The option "0"
must be like this:

 If (Daten == '0')
  {
    lcd.clear();
  }
