Servo Motors PWM pins, Arduino Uno I wanted to understand how people are connecting a servo motor to pins without PWM, so I went searching and I read that the Servo library uses the timer1 of pin 9 and pin 10 to be able to use other pins.

I would like to ask some questions about this. 


Could I connect a servo motor on pin 12 by emulation of the library, and another servo on pin 9, another on pin 10 and another on pin 11 at the same time?
Or using the Servo library the PWM in pin 9 and 10 stops working? 
I could then through library emulation connect one servo on pin 7, another on 8, another on 12 and another on 13 ? 
4 emulations at the same time?
Have you read the Servo library page? 

The library support upto 12 servos outputs. You can use any pin you want. 

The library disables analogWrite() (PWM) functionality on pins 9 and 10.
