You better use the circuit diagram in #8.
I'm a little concerned that the 2N3904 will not be strong enough to switch the relay coil. May need to replace with PN2222A or other.
2NAAAA will these work?
I understand this circuit a little better than the other. Does the led go in series after the diodes to the far right?
EDIT: In the code, you may need to temporarily change the pulse interval from 40ms to 100ms to see the LEDs blink (pulse) a bit brighter.
I'd leave the test LEDs in place, also the long delay. Then change resistor values if required, and finally clean up.
