Hi, I'm trying to find a way to connect my iRobot Roomba vacuum cleaner to my alarm system. This way, the Roomba can start every time the alarm is activated (when I leave the house)
I have a Smartplug connected to the alarm system, which can turned on or off - so my question is: is there any way the Arduino can send a signal to a servo motor to push a physical button, when a smart plug is powered on or off?
I have to admit, when I came into this thread I was hoping that we were talking about some sort of attack Roomba that came on when the alarm went off and attacked whoever was coming in.
Attacking the dirt 
stianj Just be careful some alarm systems use motion detectors which will start the alarm
if something is moving in the house, make sure you got infra red sensors. That's in case you got only
windows and doors sensors.

This can definitely be done. Simple program actually, use the smart plug to do the work. Use a wall adapter to power the Arduino from the smart plug. Program it so that when it comes on, it simply moves a servo down and back up again. Look at the sweep example, that's got all you need. You may need to change the angles it runs to from 0-180 to something else, but that should be pretty self evident what to do from the code and comments. And you would want to move the code from loop up into setup so it only runs once. You'd have nothing in the loop functionloop(){}I have to admit, when I came into this thread I was hoping that we were talking about some sort of attack Roomba that came on when the alarm went off and attacked whoever was coming in.
Thanks for the reply, very useful! I will definitely give this a shot.
Hehe, maybe that's the next step - to attack the burglars!
You can possibly send start code via IR LED instead of pressing the button.
