Trying to make IR controlled RGB strip. PWM pins of micro are connected to n-channel mosfet-s.
Everything works as expected only blue (pin 10) wont change brightness gradually, just from 0 to 100 and then if increased to 255. Tried to move to pin 3 but same thing happens.

#define DECODE_RC5
#include <Arduino.h>
#include "PinDefinitionsAndMore.h"

#include <IRremote.h>
int bila = 6;
int crvena = 3;
int zelena = 9;
int plava = 10;
int r = 5;
int g = 5;
int b = 5;
int w = 5;
void setup() {


pinMode(bila, OUTPUT); 
pinMode(crvena, OUTPUT); 
pinMode(zelena, OUTPUT); 
pinMode(plava, OUTPUT);
    Serial.begin(115200);
    
    IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK, USE_DEFAULT_FEEDBACK_LED_PIN);
}

void loop() {
  analogWrite(plava, b);
  analogWrite(bila, w);
  analogWrite(crvena, r);
  analogWrite(zelena, g);
            if (r < 0) {r = 0;}
            if (r > 255) {r = 255;}
            if (g < 0) {g = 0;}
            if (g > 255) {g = 255;}
            if (w < 0) {w = 0;}
            if (w > 255) {w = 255;}
            if (b < 0) {b = 0;}
            if (b > 255) {b = 255;}

???
p.s. ir receiver is connected to pin 2.

What MOSFETs are you using? Are they the logic level type you need to work with a microcontroller?

Also, you loop() never checks to see if you have actually received a valid command before processing. Look at the IRremote examples.

You can probably more easily use a switch statement vs. all those if/elseif/ clauses. It is a matter of taste/style.

The PWM of pin 10 might use the same timer as the IRRemote library. Can you make a small test-sketch without the IRRemote library to check if the blue led can change gradually ?
