I am trying to use my DHT11 Humidity and temperature sensor and as I am trying to compile and upload the program to my arduino uno it gives me the followoing error:
"Error compiling for board Arduino Uno."
#include <DHT.h>
#include <DHT_U.h>
#define dht_apin A0
dht DHT;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
delay(500);
Serial.println ("DHT11 Humidity & Temperature Sensone\n\n");
delay(1000);
}
void loop() {
// put your main code here, to run repeatedly:
DHT.readll(dht_apin);
Serial.print ("humidity = ")
Serial.print(DHT.humidity);
Serial.print ("temperature = ");
Serial.print (DHT.temperature);
Serial.println ("C");
delay (1000);
}
Hi @amito55. I'm going to ask you to post some additional information that might help us to identify the problem.
Please do this:
If you don't still have the IDE or web editor open with the error present, repeat the process that generated it.
You now need to copy the full and exact text of the output. The procedure for doing this is different depending on which Arduino development software you are using:
Arduino IDE 1.x: Click the Copy error messages button on the right side of the orange bar in the IDE.
Arduino IDE 2.x: Right click on the black "Output" pane at the bottom of the IDE window and then select Copy All from the context menu.
Arduino Web Editor: Click the icon that looks like two pieces of paper at the top right corner of the black console window Web Editor.

Click the </> icon on the post composer toolbar. This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V. This will paste the compilation output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Hey, thanks for fast response!
the error message is this:
