I used circuits.io for simulations (https://circuits.io/circuits/4588121-timer-1).
If you run the simulation, it's supposed to indicate something close to 0V until 4,4s, 5V between 4,4s and 6,1s, and so on...
Imagine your load (Arduino) is connected in parallel to the multimeter.
I updated the images once again. In previous imagens I intented to show that the relay opened/closed periodically (which was indicated on a resistance meter). Now it shows that the voltage at the load oscilates periodically.
I realized that the connections of relay terminals was wrong in the schematics (its terminals were short-circuited). I corrected the images on Step 3 and 4 and now it should work.
Please test If your relay is working (without using the timer circuit). Although most relays have two possible outputs (normally open and normally closed) some times only one of them work...
If it doesn't work after those verifications, let me know and I'll send you an e-mail.
I've never tried to use those libraries. I'll try to use one to see if there is an improvement in the performance.
