yes
if(digitalRead(buttonPin) == HIGH)
{
i want { servo to run 180 degree }
}
If motor 1 is 'in mid cycle', then i press switch 2 then motor 1 will stop
only one servo will run at a time so it will not will damage Arduino
Okay, be forewarned bad things can happen.
You do know 'servos always draw power'.
You should 'never' power a motor from your Arduino!
If motor 1 is 'in mid cycle', then i press switch 2 then motor 1 will stop
Stop where it currently is or go to 0 degrees first?
And
If motor 2 is 'in mid cycle', then you press switch 1 then motor 1 will stop?
