Hey guys I'm having some problems using the function analogWrite. I'm developing a program that get data from a remote control (infrared) to adjust the led brightness. But it seens that the PWM is not working, I tested other programs and they worked very well, so it's not a problem with the board. The just turn's on when I send 255 to the function analogWrite, values between 0-254 does nothing. I will post the code here, so if anyone sees the error, please tell me! Obs: pinoLed = ledpin


----------------------------------------------------
#include <IRremote.h>

#define Botplay 16761405
#define Botmais 16754775
#define Botmenos 16769055
#define Bot1 16724175
#define Bot2 16718055
#define Bot3 16743045
#define Bot4 16716015
#define Bot5 16726215
#define Bot6 16734885
#define Bot7 16728765
#define Bot8 16730805
#define Bot9 16732845
#define Bot0 16738455


int RECV_PIN = 2;
int pinoLed = 3;
int cont1 = 0;
int cont2 = 0;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()
{
  Serial.begin(9600);
  Serial.flush();
  pinMode(pinoLed, OUTPUT);
  irrecv.enableIRIn(); // Start the receiver
}

void loop() {
  if (irrecv.decode(&results)) {

    if(results.value != Botplay){
          cont1 = cont1*10;
    }
    if(results.value == Botplay){
      Serial.print("cont1 ");
      Serial.println(cont1);
      cont1 = constrain(cont1,0,255);
      Serial.print("cont1 ");
      Serial.println(cont1);

      cont1 = 0;
      cont2 = 0;

      cont1 = cont1 + 6;
      cont2 = cont2 + 1;
    }
    if (results.value == Bot7){
      Serial.println(7);
      cont1 = cont1 + 7;
      cont2 = cont2 + 1;
    }
    if (results.value == Bot8){
      Serial.println(;
      cont1 = cont1 + 8;
      cont2 = cont2 + 1;
    }
    if (results.value == Bot9){
      Serial.println(9);
      cont1 = cont1 + 9;
      cont2 = cont2 + 1;

    Serial.print("contador1 :  ");
    Serial.println(cont1);
    Serial.print("contador2 :  ");
    Serial.println(cont2);
    
    if (cont2>=3){
      cont1 = constrain(cont1,0,255);
      analogWrite(pinoLed, cont1);
      cont1 = 0;
      cont2 = 0;
    }
    
    delay(1000);
    irrecv.resume(); // Receive the next value
  }
}

Problem solved, changed the ledpin to pin 9. The IRremote lib uses timer2, that uses pins 3 and 11...
