vibrator is a good thing. it has multi-funtionality . :)
Now the vibrator we choose is the one which looks like this:

I am testing this vibrator which is neat.
const int vibratorPin = ; void setup()
{
pinMode(vibratorPin, OUTPUT);
} void loop()
{
// make it vibrate
digitalWrite(vibratorPin,HIGH);
delay();
// make it not vibrate
digitalWrite(vibratorPin,LOW);
delay();
}
make it run!
then you will see it vibrate every 1 sec.
