oh no, i really could not make it work...the reason why it blinked is because the black pin was always low...
somebody wrote a commen about my circuit and he said:
"You want the resistor and diode to be in series. The resistor connects to 5v and the cathode of the diode to the Black wire. You will want reduce the value of the resistor to around 470 ohms if you want the LED to be brighter.

Leave the 10k resistor connected to the anode of the diode, but don't connect anode and resistor to the Black wire. Remove the cathode from GND and connect it to the Black wire."

i ont understand his english
