Semafor + ora, data, temperatura

Buna ziua.
Am facut un proiect in Arduino Uno cu un semafor iar pe un lcd sa se afiseze ora, data si temperatura.
Cum pot face ca sa mearga simultan semaforul si lcdul ?

#include <DS3231.h>
#include <Wire.h>
#include <dht.h>
#include <LiquidCrystal_I2C.h> // includes the LiquidCrystal Library
#include <Servo.h>
DS3231 rtc(SDA, SCL);
unsigned long previousMillis = 0;
const long interval = 1000;
int ledState = LOW;
#define BACKLIGHT_PIN 13
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7); // 0x27 is the I2C bus address for an unmodified backpack
Servo servo;
int angle;
dht DHT;
#define dht_apin A0
void setup() {
rtc.begin(); // Initialize the rtc object
pinMode(8, OUTPUT); //rosu
pinMode(9, OUTPUT); //galben
pinMode(10, OUTPUT); //verde
//rtc.setDOW(JOI);
//rtc.setTime(20,14,00);
//rtc.setDate(01,02,2018);

lcd.begin(16,2);
lcd.setBacklightPin(3, POSITIVE); //aprindem lumina de fundal
lcd.setBacklight ( HIGH ); // lumina de fundal on
lcd.print("Buna ziua");
lcd.setCursor(8,1);
lcd.print("Razvan!");
delay(1000);
lcd.clear();
pinMode(LED_BUILTIN, OUTPUT); //luminare led Arduino
}
void loop()
{
timp();
semafor();
temp();
semafor();
data();
semafor();

}
void timp(void)
{
lcd.home (); // set cursor to 0,0
lcd.setCursor (0, 0); // go to start of 1st line
delay(100);
lcd.setBacklight( LOW );		 // Backlight off
lcd.setBacklight( HIGH );	 // Backlight on
lcd.print("Ora: ");
lcd.print(rtc.getTimeStr());
lcd.setCursor(11,0 );
lcd.print(" ");

lcd.setCursor(0,1);
lcd.print("Ziua: ");
lcd.print(rtc.getDOWStr());
lcd.setCursor(15,1); //elimina "7" de la data (an)
lcd.print(" ");
lcd.setCursor(14,1); //elimina "7" de la data (an)
lcd.print(" ");

delay (10000);

}
void temp(void)
{
lcd.clear();
DHT.read11(dht_apin);
lcd.setCursor (0,0);

lcd.print("Temp: ");
lcd.print(DHT.temperature);

lcd.print(" C");
delay(10000);

lcd.clear();
lcd.print("Data: ");
lcd.print(rtc.getDateStr());

delay(5000);
}
void data(void)
{
lcd.print("Data: ");
lcd.print(rtc.getDateStr());

delay(5000);
}
void semafor(void)
{
   digitalWrite(10,HIGH); // verde
	delay(5000);
	digitalWrite(10,LOW);
	delay(0);
	digitalWrite(9,HIGH); //galben
	delay(800);
	digitalWrite(9,LOW);
	delay(00);
	digitalWrite(8,HIGH); //rosu
	delay(9000);
	digitalWrite(8,LOW);
	delay(00);
	digitalWrite(9,HIGH); //galben
	delay(800);
	digitalWrite(9,LOW);
	delay(00);
}

}

Cum as putea sa rezolv problema ?

Ai nevoie de pini separati pentru semafor si pentru LCD, iar codul trebuie sa poata sa ruleze si seamforul si programul pt lcd in acelasi timp, nu secvential. Cel mai ine ar fi 2 proiecte seaprate pe care le rulezi in acelasi timp, dar nu stiu daca se poate face asta pe Arduino.

OK,
Daca am inteles problema ta, ar fi faptul ca ai acele delay care te impiedica sa treci mai departe:
ai avea 2 variante:

1. Interrupts si setezi 2 ISR in functie de un timer
https://www.allabout...pts-on-arduino/
2 Multi threading
https://create.ardui...tutorial-dd2c37

Acum depinde de tine care sa o folosesti, ideea ar fi ca intre threaduri trb sa sti si mod de functionare si transmitere eventuri ca sa ai o succesiune anume, iar la interrupts cateva globale si esti rezolvat

Daca nu esti familiarizat ca OS end "chestii" mergi pe interrupts

Da, asta am nevoie. Vreau ca semaforul sa mearga in treaba lui ( sa nu aiba nicio legatura cu LCD-ul )

Mda. Inca nu sunt asa bine familiarizat cu Arduino. Multumesc ! Am sa revin cu un update cand am sa rezolv problema.

   delay(1000);
   lcd.clear();
  
   digitalWrite(carGreen, HIGH); //porneste culoare verde masini
   digitalWrite(pieRed, HIGH); //porneste culoare rosie de la pietoni
   pinMode(LED_BUILTIN, OUTPUT); //luminare led Arduino
}
void loop()
{  
   timp();
   data();
   temp();
	int state = digitalRead(button);
		if(state == HIGH && (millis() - changeTime)> 5000) // daca au trecut 5 secunde de la ultima apasare, se aprinde verde la pietoni

			   changeLights();

  digitalWrite(carGreen, HIGH);
  changeTime = millis(); // memoreaza timpul de la ultima schimbare de semafor
  //terminare
}

Am facut asa. 90% functioneaza cum vreau eu. ( am mai adaugat un semafor pentru pietoni pe care il actionez de la un buton ).

Poti incerca si abordarea aceasta:

Mda. Tot nu ma descurc.

Aici am gasit un program interesant.
https://github.com/D...LCDTrafficLight
Afiseaza pe ecran mesaje in functie de culoare semaforului.   "Stai", "Atentie", "Du-te".

Trebuie sa incerc maine sa-l modific pe al meu in functie de acesta. Sa-l fac ca atunci cand se schimba culoarea semaforului sa se schimbe si mesajul de pe LCD.
