I have been having an error with this code can someone help

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

#include <dht.h>
#include <LowPower.h>

#define dataPin 2
dht DHT;

void setup() {
Serial.begin(9600);
pinMode(LED_BUILTIN,OUTPUT);
digitalWrite(LED_BUILTIN,LOW);
}

void loop() {
Serial.println("Get Data From DHT11");
delay(1000);
digitalWrite(LED_BUILTIN,HIGH);
int readData = DHT.read11(dataPin); // DHT11

float t = DHT.temperature;
float h = DHT.humidity;

Serial.print("Temperature = ");
Serial.print(t);
Serial.print(" C | ");

Serial.print("Humidity = ");
Serial.print(h);
Serial.println(" % ");

delay(2000);
Serial.println("Arduino:- I am going for a Nap");
delay(200);
digitalWrite(LED_BUILTIN,LOW);
LowPower.idle(SLEEP_8S, ADC_OFF, TIMER2_OFF, TIMER1_OFF, TIMER0_OFF,
SPI_OFF, USART0_OFF, TWI_OFF);
Serial.println("Arduino:- Hey I just Woke up");
Serial.println("");
delay(2000);
}

Try:

DHT dht;
3

exit status 1
no matching function for call to 'DHT::DHT()'

4

Guessing:

DHT dht(dataPin);
5

Why three?

Please remember to use code tags when posting code

I've been having issues at first saying dht.h: no such file or directory. Then I tried searching for libraries and it disappeared, now this shows.

Still the same error

Arduino Sleep Modes and How to use them to Save the Power this is the project I'm working on, but having trouble with the codes

That's odd, post the code that gave you that.

Arduino Sleep Modes and How to use them to Save the Power here is the link of the project that im working, the code is there

@mmmmm09, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with your project. See
About the Installation & Troubleshooting category.

Can you please edit your opening post, select all code and click the </> button to apply code tags; next save your post.

Hi,
use this library :

and this your code:

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

#include <dht.h>
#include <LowPower.h>

#define dataPin 2
dht DHT;

void setup() {
  Serial.begin(9600);
  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, LOW);
}

void loop() {
  Serial.println("Get Data From DHT11");
  delay(1000);
  digitalWrite(LED_BUILTIN, HIGH);
  int readData = DHT.read11(dataPin); // DHT11

  float t = DHT.temperature;
  float h = DHT.humidity;

  Serial.print("Temperature = ");
  Serial.print(t);
  Serial.print(" C | ");

  Serial.print("Humidity = ");
  Serial.print(h);
  Serial.println(" % ");

  delay(2000);
  Serial.println("Arduino:- I am going for a Nap");
  delay(200);
  digitalWrite(LED_BUILTIN, LOW);
  LowPower.idle(SLEEP_8S, ADC_OFF, TIMER2_OFF, TIMER1_OFF, TIMER0_OFF,
                SPI_OFF, USART0_OFF, TWI_OFF);
  Serial.println("Arduino:- Hey I just Woke up");
  Serial.println("");
  delay(2000);
}

and tell me how it was...

Thanks, there are no more code errors. However, the voltage and current being shown by the ammeter is constant even when it goes to sleep mode.
