Hi guys,
Thinking about how to automate my microwave, I concluded that there is no such way unless you remove the buttons panel and risk to screw it all...
So I chose the hard way, just for fun XD I liked so much the gadget I made that I decide to make a video.
Hope you enjoy it:
Cheers!

Haha, that's pretty good.
Your microwave is good for this method, a lot of other microwaves would require a button presser that could move in two axes, to hit all the buttons on the microwave.
(p.s.: mario music?)
Yeah!
I think the best method should be to add a lot of time (usually possible with only start button) and cancel after an arduino count.
It saves you from having to press a lot of numbers.
And Yes, Mario music! 
Excellent idea!
