Arduino and relay

Hi all,
i want to switch a relay with the arduino UNO, but i wont switch far enough to make or break a contact.
When i connect the relais directly to 5v (power pin) and gnd i worked.
Relais info: JQX-14FC-2C (6vdc)
I tryed the digital pins 13,12,11 and 10.
And of course GND

And yes i connected it the right way.

int led = 10;

void setup() {                
 pinMode(led, OUTPUT);   
}

void loop() {
  digitalWrite(led, HIGH)
}

Any ideas?

you are overloading to pin.
make I/Opin control a transistior..that controls the relays coil.

Odd because there is no "right way round" to connect a coil.
As well as a transistor you need a diode across the coil.

I tryed the digital pins 13,12,11 and 10.

So those are the pins you have damaged then.
