Combine bmp280 code and blynk switch code

Need Help With My Project
1

i want to make a project that my room lamp are controlled by phone and i can see the temperature, pressure, and altitude but i got problem when combining these two codes

below is my switch code


#define BLYNK_PRINT Serial


#include <WiFi.h>
#include <BlynkSimpleEsp32.h>

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

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "xxxx";
char pass[] = "xxxxxxx";

// Set your LED and physical button pins here
const int ledPin1 = 13;
const int ledPin2 = 14;
const int ledPin3 = 15;
const int ledPin4 = 16;
const int btnPin1 = 32;
const int btnPin2 = 33;
const int btnPin3 = 34;
const int btnPin4 = 35;

BlynkTimer timer;
void checkPhysicalButton();

int led1State = LOW;
int btn1State = HIGH;

int led2State = LOW;
int btn2State = HIGH;

int led3State = LOW;
int btn3State = HIGH;

int led4State = LOW;
int btn4State = HIGH;

// Every time we connect to the cloud...
BLYNK_CONNECTED() {
  // Request the latest state from the server
  Blynk.syncVirtual(V12);
  Blynk.syncVirtual(V13);
  Blynk.syncVirtual(V14);
  Blynk.syncVirtual(V15);

  // Alternatively, you could override server state using:
  //Blynk.virtualWrite(V12, led1State);
  //Blynk.virtualWrite(V13, led2State);
  //Blynk.virtualWrite(V14, led3State);
  //Blynk.virtualWrite(V15, led4State);

}

// When App button is pushed - switch the state
BLYNK_WRITE(V12) {
  led1State = param.asInt();
  digitalWrite(ledPin1, led1State);
}
  
 BLYNK_WRITE(V13) {

  digitalWrite(ledPin4, led4State);
}

void checkPhysicalButton()
{
  if (digitalRead(btnPin1) == LOW) {
    // btn1State is used to avoid sequential toggles
    if (btn1State != LOW) {

      // Toggle LED state
      led1State = !led1State;
      digitalWrite(ledPin1, led1State);

      // Update Button Widget
      Blynk.virtualWrite(V12, led1State);
    }
    btn1State = LOW;
  } else {

}

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

  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8442);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8442);

  pinMode(ledPin1, OUTPUT);

  // Setup a function to be called every 100 ms
  timer.setInterval(500L, checkPhysicalButton);
}

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

and below is my bmp280 sensor code

#include <SPI.h>
#include <WiFi.h>
#include <BlynkSimpleEsp32.h>
#include <SimpleTimer.h>
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BMP280.h>


char auth[] = "...";
char ssid[] = "...";  //Enter your WIFI Name
char pass[] = "...";  //Enter your WIFI Password

#define BMP_SCK 18
#define BMP_MISO 19
#define BMP_MOSI 23
#define BMP_CS 5

Adafruit_BMP280 bme; // I2C

SimpleTimer timer;

void sendSensor()
{
  float a = bme.readTemperature();
  float b = bme.readPressure()/100;
  float c = bme.readAltitude(1015.80);
  // You can send any value at any time.
  // Please don't send more that 10 values per second.
  Blynk.virtualWrite(V7, a);  //V7 is for Temperature on BMP280
  Blynk.virtualWrite(V8, b);  //V8 is for Pressure on BMP280
  Blynk.virtualWrite(V9, c);  //V9 is for Altitude on BMP280
}

void setup()
{
  Serial.begin(9600); // See the connection status in Serial Monitor
  Blynk.begin(auth, ssid, pass);

  bme.begin();

  // Setup a function to be called every second
  timer.setInterval(1000L, sendSensor);
}

void loop()
{
  Blynk.run(); // Initiates Blynk
  timer.run(); // Initiates SimpleTimer
}

please help me who can combine these two code, sorry for bad english

Where exactly did these two pieces of code come from?

How are you controlling your room lamp? Presumably using a relay, but is that active HIGH or LOW? Is it a single lamp, or three lamps as in the sketch?
Are you using a physical switch to turn the lamp(s) on and off, or just the Blynk app?

What sort of MCU are you using?

Pete.

sorry i post the wrong code, but i have already post the right code

  1. these code are come from this community and i want to combine these two codes for my bedroom

  2. i using relay, the relay are active low, i have four lamp at my room

  3. i want to use both of them for my project, physical button that syncronized with Blynk app

  4. i use esp32 NodeMCU module

would you help me to finish this project?
