PWM not working

Projects General Guidance

I have a transistor w/ motor on pin 10 on my arduino duilminove. I am trying to analogWrite() it. I loaded the fade example and it worked great. I added it to my code of my project and it does not work, only when it is set to 255 it goes. what can cause this? I have the servo library in use can this cause this?

here is my code

#include <Servo.h> 
 
Servo myservo;  // create servo object to control a servo 



const int xPin = 2;		// X output of the accelerometer
const int yPin = 3;		// Y output of the accelerometer

  int  incomingByte = 0;

int r = 7;
int g = 6;
int b = 5;
int bulb = 9;
int vibe1 = 10;



void setup() 
{
  Serial.begin(9600);
   myservo.attach(11);
         //pinMode(10, OUTPUT);
  pinMode(xPin, INPUT);
  pinMode(yPin, INPUT);
    pinMode(r, OUTPUT);
      pinMode(g, OUTPUT);
        pinMode(b, OUTPUT);
          pinMode(bulb, OUTPUT);
     analogWrite(10, 254);
}

void loop() {
  // variables to read the pulse widths:
  int pulseX, pulseY;
  // variables to contain the resulting accelerations
  int accelerationX, accelerationY;
  
  // read pulse from x- and y-axes:
  pulseX = pulseIn(xPin,HIGH);  
  pulseY = pulseIn(yPin,HIGH);
  
  // convert the pulse width into acceleration
  // accelerationX and accelerationY are in milli-g's: 
  // earth's gravity is 1000 milli-g's, or 1g.
  accelerationX = ((pulseX / 10) - 500) * 8;
  accelerationY = ((pulseY / 10) - 500) * 8;
int s = map(accelerationX,-1023,1023,1,1000);

Serial.write(s / 256);
Serial.write(s % 256);
 s = map(accelerationY,-1023,1023,1,1000);
Serial.write(s / 256);
Serial.write(s % 256);
 s = map(analogRead(A0),0,1023,1,1000);
Serial.write(s / 256);
Serial.write(s % 256);
 s = map(analogRead(A1),0,1023,1000,1);
Serial.write(s / 256);
Serial.write(s % 256);
 s = map(analogRead(A2),0,1023,1,254);
Serial.write(s);



if (Serial.available() > 0) 
{
    incomingByte = Serial.read();
    if (incomingByte == 200)
    {
      digitalWrite(bulb, HIGH);
    } 
     if (incomingByte == 201)
    {
      digitalWrite(bulb, LOW);
    } 
    
        if (incomingByte == 202)
    {
      digitalWrite(b, HIGH);
    } 
     if (incomingByte == 203)
    {
      digitalWrite(b, LOW);
    } 
    
        if (incomingByte == 204)
    {
      digitalWrite(g, HIGH);
    } 
     if (incomingByte == 205)
    {
      digitalWrite(g, LOW);
    } 
    
        if (incomingByte == 206)
    {
      digitalWrite(r, HIGH);
    } 
     if (incomingByte == 207)
    {
      digitalWrite(r, LOW);
    } 
      if (incomingByte == 208)     {analogWrite(10, 50);} 
      if (incomingByte == 209)     {analogWrite(10, 90);} 
      if (incomingByte == 210)     {analogWrite(10, 140);} 
      if (incomingByte == 211)     {analogWrite(10, 190);} 
      if (incomingByte == 212)     {analogWrite(10, 220);} 
      if (incomingByte == 213)     {analogWrite(10, 255);} 
    
    
    
        if (incomingByte < 180)
    {
       myservo.write(incomingByte);    
    } 
    
     
    
   
  }

  delay(1);
}

//pinMode(10, OUTPUT);

why did you comment this out?

in the playground it said you don't have to call that function so i tried commenting it out it does not work either way

I have the servo library in use can this cause this?

Reference material is provided that you could read - Servo - Arduino Reference

On boards other than the Mega, use of the library disables analogWrite() (PWM) functionality on pins 9 and 10, whether or not there is a Servo on those pins.
