Hi, i'm new to the Arduino world and need some help understanding this library. i've the done the LED and Servo examples that come standard with the software. My project involves controlling 2 servos with a PS2 controller. i got it working using a modified version of Bill Porter's example sketch that came with his library. but now i'd like to control the speed of the servos. i'm very new to this and wondered if anyone can help me and explain how to use the VarSpeedServo library in layman's terms.
Here's what i have so far, but i get a lot of errors:
#include <VarSpeedServo.h>
#include <PS2X_lib.h> //for v1.6
PS2X ps2x; // create PS2 Controller Class
//right now, the library does NOT support hot pluggable controllers, meaning
//you must always either restart your Arduino after you conect the controller,
//or call config_gamepad(pins) again after connecting the controller.
int error = 0;
byte type = 0;
byte vibrate = 0;
int LX;
int LY;
VarSpeedServo myservo; // create servo object to control a servo
VarSpeedServo myservo2;
void setup(){
Serial.begin(57600);
//CHANGES for v1.6 HERE!!! **************PAY ATTENTION*************
error = ps2x.config_gamepad(13,11,10,12, true, true); //setup pins and settings: GamePad(clock, command, attention, data, Pressures?, Rumble?) check for error
{
myservo.attach(5,0,180); // attaches the servo on pin 9 to the servo object
myservo2.attach(6,0,180);
}
if(error == 0){
Serial.println("Found Controller, configured successful");
Serial.println("Try out all the buttons, X will vibrate the controller, faster as you press harder;");
Serial.println("holding L1 or R1 will print out the analog stick values.");
Serial.println("Go to www.billporter.info for updates and to report bugs.");
}
else if(error == 1)

you should call this at least once a second
