So I've never programmed motor control using the Arduino and have in fact just started using the Arduino so any help getting started or examples would be awesome. For specifics I'm using 4 of these motors Park 480 Brushless Outrunner Motor, 1020Kv
[http://www.e-fliterc.com/Products/Default.aspx?ProdID=EFLM1505]. All I need to do is drive them so if I'm getting everything right I only need 4 PWM pins instead of 8. They'll be set up in a cross pattern and will determine direction and breaking by which of the motors are active. I figured this would be easier to start off with. Eventually I'd like them to be controlled by an IR for obstacle avoidance.

For more info eventually I'll be using the Infrared Proximity Sensor Long Range - Sharp GP2Y0A02YK0F [http://www.sparkfun.com/products/8958] and the PING))) Ultrasonic Distance Sensor [http://www.parallax.com/Store/Sensors/ObjectDetection/tabid/176/CategoryID/51/List/0/SortField/0/Level/a/ProductID/92/Default.aspx] in order to do obstacle navigation. But for now it would be alright if it was just controlled via an input or I here you an us Processing to do a user interface [?] if that's true then something like that to start off with would be fine.


Normally, motors like that are driven using an RC-type ESC, and the Servo library. Something like http://www.e-fliterc.com/Products/Default.aspx?ProdID=EFLA312B.


Would something like that be able to handle more then 1 brushless motor?


I don't think so. You would have one esc per motor.

No, the ESC uses back EMF sensing to maintain phase-lock, you cannot parallel motors.

Be warned these motors are extremely powerful, treat as you would a power tool.
