Hello @monica.hernandezc 
!
Following the code on the article you shouldn’t have any issue, also you can find the code clicking here.
Remember, it’s important that you create in Ubidots a device called “pet” and a variable called “dispenser” before upload the code, because you’re going to subscribe it to this device to be able to control the servo.
I hope this would help you!
Best Regards
