Automated oil diffuser with google home

I like to have my essential oil diffuser on when I wake up and when I go to bed.
So I decided to make it automated and work with google home via app. this way I can use it with my routines and let it go on even before I wake up.

All you need is:
- a essential oil diffuser with a bottom diameter of 190mm
- arduino uno with 3 male/male dupont cables
- sg90 servo motor
- smart home socket. I got one from hombli (https://www.bol.com/nl/nl/p/smart-socket-duo-eu/9200000119483587/) the site is in dutch, for reference, to see what it looks like

and the 2 printed parts:
- the diffuser stand with cap for the arduino
- the extender for the servo motor

The code for the arduino is in the section below.
what it does is, when the arduino gets powered on, the servo motor spins twice, so the diffuser is on for 2 hours
