Using Arduino Programming Questions

Hi,

I am using PWM to control the speed of two servo motors. How can I have two PWM values, one for each motor?

you could try using analogWrite() selecting the pins controlled by different timers. I've listed the pins controlled by the 3 timers for a UNO.

  • Pins 5 and 6: controlled by Timer 0
  • Pins 9 and 10: controlled by timer 1
  • Pins 11 and 3: controlled by timer 2

Hope that helps

Servos or servomotors? I think you mean servos, in which case the Servo library is the obvious thing to use.

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html .
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

Thanks.. Tom... :slight_smile:
