In this tutorial, I’ll first go into a little background about humidity, then I’ll explain how the DHT11 measures humidity. After that, I’ll show you how to connect the DHT11 to an Arduino and give you some example code so you can use the DHT11 in your own projects. Change the pin assignment to pin 3 and the program should compile, upload to your Arduino and flash the LED if everything is wired properly on your breadboard. Int ledPin = 3; We’re using Digital Pin 3 on the Arduino.
I am trying to make a script that allows me to change the duration and tone of a speaker using and IR remote. For some reason I keep getting a Error Compiling for board Arduino/Genuio Uno error. Here's my code:
- Code: Select all | TOGGLE FULL SIZE
// Include IR Remote Library by Ken Shirriff
#include <IRremote.h>
// Define sensor pin
const int RECV_PIN = 9;
// Define integer to remember toggle state
int togglestate = 0;
int duration = 500;
int soundTone = 500;
// Define IR Receiver and Results Objects
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup(){
// Enable the IR Receiver
irrecv.enableIRIn();
// Set LED pins as Outputs
pinMode(8, OUTPUT);
}
void loop(){
if (togglestate 1){
tone(8,soundTone);
delay(duration);
noTone(8);
delay(duration);}
else{
noTone(8);}
if (irrecv.decode(&results)){
switch(results.value){
case 0x3AFB26D4: //Down Button
if(soundTone > 50){
soundTone = soundTone - 50;
delay(100);}
else{
soundTone = soundTone;
delay(100);}
break;
case 0xE246AFCA: //Up Button
if (soundTone < 55){
soundTone = soundTone + 50;
delay(100);}
else{
soundTone = soundTone;
delay(100);}
break;
case 0x4D43596A: //Left Button
if (duration > 0){
duration = duration - 100;
delay(100);}
else{
duration = duration;
delay(100);}
case 0xBB0EDD22: //Right Button
if (duration < 1500){
duration = duration + 100;
delay(100);}
else{
duration = duration;
delay(100);}
case 0x406A954D: //Power Button
if(togglestate0){
togglestate = 1;
delay(300);}
else {
togglestate = 0;
delay(300);}
break;
}
irrecv.resume();
}
}
Here's the error:
- Code: Select all | TOGGLE FULL SIZE

Any help would be awesome. Thanks!
I am using arduino IDE since a year with old version 1.5.8After I updated the version of arduino (due to some errors in old version) I am getting this error even when I compile an empty default sketch:
I have tried many solutions on forum and stackoverflow Nothing has solved my error.
What should I do ???
ALso, I suspect NPAV antivirus which I installed in my laptop recently maybe causing the error, since the scan shows some arduino files as threats... But I am not sure if that is the issue. And as NPAV is a paid software I didn't remove it to see if the error goes. though i tried disabling NPAV which didn't help.

Solved the issue I was guessing it's the new antivirus issue...Thus uninstalled it Working perfectly now
