controling more Servos at the same time coding trouble

Using Arduino Motors, Mechanics, Power and CNC
1

Hi guys

I'm working with some servoes at the moment and I need some of your awesome advises.
I want to control 2-3 Servos at the same time with 2-3 potentiometers. I can make it work when I use Processing or MAX/ msp with my arduino. but i also need it to work only with the Arduino.

To begin I just want each servo to sweep between 0-180 degrees. The speed of each servo should be controlled by one of the 2-3 potentiometers. so servo1 is controlled by pot1 and servo2 is controlled by pot2
I got this working but the problem for me is that they take one servo at a time and i need it to be done at the same time.
So my question is how I combine this code so they all can be controlled at the same time.

hope you can help.
All the best

for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree

val=analogRead(potpin);
val=map(val,0,1023,20,1);
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(val); // waits (val)ms for the servo to reach the position
}
for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
val=analogRead(potpin);
val=map(val,0,1023,20,1);

}

myservo1.write(pos1); // tell servo to go to position in variable 'pos'
delay(val1); // waits (val)ms for the servo to reach the position
}
for(pos1 = 180; pos1>= 1; pos1 -=1) // goes from 180 degrees to 0 degrees
{
val1=analogRead(potpin1);
val1=map(val1,0,1023,20,1);

}

I also have an other code where they work at the same time but then they are not sweeping, but just setting the position of the servo.
Best code for me is if i could make a code where i had both sweeping where the poti controls the speed and the if i pushed a button it would change to this code and then the poti just controls the position. sorry if there is to many questions the most important is the one in the post before but I just like to put the ideas up there :slight_smile:
Thx again
