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 = 8; void setup() { pinMode(vibratorPin, OUTPUT); } void loop() { // make it vibrate digitalWrite(vibratorPin,HIGH); delay(1000); // make it not vibrate digitalWrite(vibratorPin,LOW); delay(1000); }
make it run!
then you will see it vibrate every 1 sec.
