Can help me to combine this two code?

Need Help With My Project

hi guys, I want to combine my code into blynk code, but after combine ,my keypad won’t function anymore
My code

#include<LiquidCrystal.h>  
LiquidCrystal lcd(2,3,4,5,6,7); 
int row[]={A0,A1,A2,A3};// Defining row pins of keypad connected to Arduino pins
int col[]={A4,A5,0,1};//Defining column pins of keypad connected to Arduino
int i,j,lcd_count,count=1,key_id=0,flag,entry=0;// See About the Program 
int col_scan;// Variable to identify a key press
int inPin = 13; //button pin
int rPin = 8; //relay pin
int val = 0;
char temp_press; // Variable to hold value of key press
char check[6],pass[6]; // See About the Program
const int buzzer = 9; //buzzer to arduino pin 9

Blynk code

#include <SoftwareSerial.h>
SoftwareSerial DebugSerial(0, 1); // RX, TX

#define BLYNK_PRINT DebugSerial
#include <BlynkSimpleStream.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "my AuthToken";

void setup()
{
  // Debug console
  DebugSerial.begin(9600);

  // Blynk will work through Serial
  // Do not read or write this serial manually in your sketch
  Serial.begin(9600);
  Blynk.begin(Serial, auth);
}

void loop()
{
  Blynk.run();
}

Thanks!

Edit, thanks for editing your code! Much easier to read :slight_smile:

Now, my first impression is that you should know and understand the PushData Blynk example in the IDE before trying to merge these sketches.

You need to understand how to remove all your functions from the loop, and put them behind a SimpleTimer timer.
Your loop should be no more than the following

void loop(){
  Blynk.run();
  timer.run();
}

Im not going to write your code, but i’ll give you a hand.

The top of your loop() contains the following:

val = digitalRead(inPin);  // read input value
  if (val == HIGH) {         // check if the input is HIGH (button released)
    digitalWrite(rPin, HIGH);  // turn LED OFF
    lcd.setCursor(0,0);
    lcd.print("UNLOCKED");
    delay(3000);              // wait for a second
    digitalWrite(rPin, LOW);
    lcd.clear();
    lcd.print("LOCKED");   
  } else {
    digitalWrite(rPin, LOW);  // turn LED ON
  }

You could, instead of putting it in the loop, setup up interupt with a callback function. This wouldn’t need to be on a timer, but you will need to be VERY careful about virtualWrite flooding.

For the sake of everyone else, I recommend you edit your first post to reflect the changes, and delete your second post with the duplicate code.
