hi,
i trying run following nodejs code, based on duino module found here: https://github.com/ecto/duino

var arduino = require("duino");
var board = new arduino.board();

var led = new arduino.led({
  board: board,
  pin: 13
});

var bleep = function() {
  led.on();
  settimeout(function() {
    led.off();
  }, 100);
}
setinterval( bleep, 1000 );

but, following error:
bleep_duino:1: error: 'var' not name type
bleep_duino:2: error: 'var' not name type
bleep_duino:4: error: 'var' not name type
bleep_duino:7: error: expected unqualified-id before ')' token
bleep_duino:9: error: 'var' not name type
