Vibrate every 20 minutes?

[Aubrie]

Hi Automate experts,

I used to use Macrodroid but discovered that Automate is much more powerful. Here's what I'd like to do:

When the phone is not plugged in:

• Play vibration pattern A at the hour mark (:00)
• Play vibration pattern B at the :20 minute mark
• Play vibration pattern C at the :40 minute mark

After searching the forums, I created this flow:

1. Flow beginning
2. Await time
   Proceed = Exact
   Time of day = time(dateFormat(Now, "H"), dateFormat(Now, "m") - (dateFormat(Now, "m") % 20) + 20)
3. Is power source plugged
   Proceed = Immediately
   • Y) loop back to #2
   • N) Vibrate with pattern A, then loop back to #2

Now, how do I make it with the three different vibration patterns?

Thank you!
