Internet of things cookbook with arduino

I am trying to set up a light sensor along with a DHT11 humidity/temperature sensor. It is from a book on how to start working with IOT and arduino. The picture is my attempt to replicate the book. I kept getting a 413 error when trying to upload more pics. Let me know if I can direct message them to you. The light sensor seems to be working fine, but I cannot get data from the DHT11. Help would be appreciated. I am also posting the code the book provided me with. here.

#include <DHT.h>
#include <DHT_U.h>

// Pins
int sensorPin = A0;
#define DHTPIN 5
#define DHTTYPE DHT11

// Initialize DHT sensor
DHT dht(DHTPIN, DHTTYPE, 15);

void setup() {

// Serial
Serial.begin(115200);

// Init DHT
dht.begin();

}

void loop() {

// Reading temperature and humidity
float humidity = dht.readHumidity();
// Read temperature as Celsius
float temperature = dht.readTemperature();

// Display
Serial.print(“Temperature: “);
Serial.print(temperature);
Serial.println(” C”);

Serial.print(“Humidity: “);
Serial.print(humidity);
Serial.println(” %”);

// Reading from analog sensor
int sensorValue = analogRead(sensorPin);
float lightLevel = sensorValue/1024.*100;

// Display
Serial.print(“Light level: “);
Serial.print(lightLevel);
Serial.println(” %”);
Serial.println();

// Wait
delay(500);

}
