16x2 LCD; showing time on first line and scrolling weather on the second line

Other Hardware Displays
1

Hello everyone,
I'd like to make clock with weather. I need to show the clock on the first line and on the second line scroll the: temperature, humidity and pressure.

  1. constantly display time on the first line
  2. Scroll the temperature to the beginning of the line
  3. Stop scrolling
  4. rewrite the temperature several times
  5. scroll the temperature away and scroll the humidity in
  6. Rewrite moisture several times
  7. Scroll the moisture away and scroll the pressure in
  8. Rewrite the pressure several times

But I need all of this without delay() or anything that suspends the code so that I can constantly check the status of the buttons.

all the other code is done, I just need to scroll the weather. here's my older code to show weather on both lines:

#include <LiquidCrystal.h>
#include <Wire.h>
#include <Adafruit_BMP085.h>
#include "DHT.h"
#define DHTPIN_22 8
#define DHTTYPE_22 DHT22
Adafruit_BMP085 bmp180;

float hum_22;
float temp_22;
float vyska;
float v;
String tlak;
String hum;
String temp;
int korekce = 32;
int x;
int z;
unsigned long previousMillis = 0;
unsigned long tlakMillis = 0;
const long interval = 5000;

DHT dht_22(DHTPIN_22, DHTTYPE_22);
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

byte stupen[] = {
  B00111,
  B00101,
  B00111,

  B00000,

  B00000
};

void setup() {
  dht_22.begin();
  bmp180.begin();
  lcd.begin(16, 2);
  lcd.createChar(0, stupen);
  delay(1000);
  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, LOW);

  unsigned long currentMillis = millis();

    tlakMillis = currentMillis;
    tlak = (bmp180.readPressure() + korekce * 100) / 100.00;

      lcd.clear();
    }
    if (z == 0) {
      lcd.setCursor(0, 0);
      lcd.print("Teplota: ");
      lcd.print(temp_22);

      lcd.setCursor(0, 1);
      lcd.print("Vlhkost: ");
      lcd.print(hum_22);
      x = 1;

    }

      lcd.write(byte(0));
      lcd.print("C");

I have some things in Czech so now you know what is that.
