The Servo.attach min and max parameters default to 544 and 2400, respectively.
These are the default pulse widths in microseconds corresponding to 0 degrees and 180 degrees.They are explained here: http://arduino.cc/en/Reference/ServoAttach
But from other websites and the Arduino Servo.writeMicroseconds reference I see that the standard signal pulse width for 0 degrees and 180 degrees are 1000 microseconds and 2000 microseconds respectively.
Description Writes a value in microseconds (uS) to the servo, controlling the shaft accordingly. On a standard servo, this will set the angle of the shaft. On standard servos a parameter value of 1000 is fully counter-clockwise, 2000 is fully clockwise, and 1500 is in the middle.
So why does it seem that for Servo.attach() the default min and max values are 544 and 2400, but the standard for most servos is 1000 and 2000?
