I think you have a power-of-ten error. Michael is referring to a 33
ohm resistor (orange-orange-black, IIRC), not a 330 ohm resistor
(orange-orange-brown). With the larger resistor, you probably won't
get enough current to operate the relay.

Without the resistor the voltage across the coil with he port set to level 7 is 7.17. When I add the resistor in (...) (25 years ago, 27-Sep-99, to lugnet.robotics)
