Third PWM channel on ATTINY85

Thanks! I was able to get it to mostly work (At least the PWM functionality)
I had to strip almost all the PIR and other code out to be able to test 3 channel PWM

#define REDPIN 0
#define GREENPIN 1
#define BLUEPIN 4
#define PIR 3


boolean human_detected = false;
unsigned long timer;
int r, g, b;

#define FADESPEED 10     // make this higher to slow down

void setup() {
  pinMode(PIR, INPUT);
  pinMode(REDPIN, OUTPUT);
  pinMode(GREENPIN, OUTPUT);
  pinMode(BLUEPIN, OUTPUT);
  analogWrite(REDPIN, 0);
  analogWrite(GREENPIN, 0);
  analogWrite(BLUEPIN, 0);
}


void loop() {

    for (r = 0; r < 255; r++) { 
      analogWrite(REDPIN, r);
      analogWrite(GREENPIN, r);
      analogWrite(BLUEPIN, r);
      delay(FADESPEED);
    }
}
