Control a motor from the arduino board with a speed controller.

I connected the speed controller (ESC) to the arduino board and I connected the black cable of the receiver connection to the GND pin of the arduino and the white cable to the Digital PWM pin number 3.

I upload a sketch that I found on this post from the Arduino Forum to the board to test the motor, but nothing happening.
After some research I discovered that is necessary adjust the minim pulse width value. From the operating instructions that came with the speed controller I find that the stop position must be within the range 800 us to 1700 us and the full-throttle position must be at least 350 us than the stop position.
I make another sketch to find the the minimum pulse width value that start the motor and closer to the 0 angle. After several attempts I found that the nearest value is 836 us.
Finally, I made the sketch that is shown below, which starts the  ESC and keeps the motor running in a loop for 30 seconds and then stop for 10 seconds.

#include <Servo.h>

Servo escservo;

long lasttime = millis();

void setup() {
  delay(1000);
  Serial.begin(9600);

  // If you connected now the battery to the ESC, send
  // the 's' character. If not send another character.
  Serial.println("Wait for your input! [s] to init...");
  while(Serial.available() <= 0) delay(1000);
  Serial.println("Start the system...");
  int incomingByte = Serial.read();
  
  // Change the min pulse width value until match the
  // lowest value needed to start the motor.
  // From the ESC operation instructions the stop position
  // must be within the range 800 us to 1700 us.
  // The value 836 us is the lowest value.
  escservo.attach(3, 836, 2400);
  
  // arm the ESC
  escservo.write(0);
  delay(5000);
  
  // If you sent the character 's'
  if(incomingByte == 115) {
    Serial.println("Traverses all angles upward and downward.");
    cycle();
    delay(1000);
  }
}

void cycle() {
  int angle;
  // Danger: Try first with a value lower than 179, eg 160
  // Gradually increase to 180.
  for(angle = 0; angle <= 160; angle++) {
    escservo.write(angle);
    delay(15);
  }
  // Decrease the angle from 180 to 0.
  for(angle = 160; angle >= 0; angle--) {
    escservo.write(angle);
    delay(15);
  }
}

void loop() {
  long duration = millis() - lasttime;

  // If the duration is great than 30 seconds,
  // stop the engine for 10 seconds.
  if(duration >= 30000) {
    escservo.write(0);
    delay(10000);
    lasttime = millis();
  }
  // Put the motor to rotate in the angle 5
  escservo.write(5);
  delay(500);
}
