Question

What would be the wiring setup and coding using an Arduino for a display of the temperature of the room it is in?

Answer 1

Coding using an Arduino for the display of the temperature of the room it is in is given below

#include <SPI.h>
#define BLYNK_PRINT Serial
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>
#include <SimpleTimer.h>
#include <dht11.h>
dht11 DHT11;
SimpleTimer timer;

char auth[] = "";        // write your auth code here
void setup()
{
  DHT11.attach(2);      // connect pin 2 to the sensor
  Serial.begin(9600);
  Blynk.begin(auth);     // start blynk server and connect to the cloud
 while (Blynk.connect() == false) {
    // Wait until connected
  }
  
void loop()
{
  int chk = DHT11.read();
   Blynk.virtualWrite(1, DHT11.temperature);  // Write values to the app
  Blynk.virtualWrite(2, DHT11.humidity);
Serial.println(DHT11.temperature);

  Blynk.run();
  timer.run();
  
}
