House Automation Question

Greetings,

I'm interested in Domotics. I would like to know if Arduino is a good choice for controlling multiple things like windows, lights, doors at the same time? If Arduino isn't good for this purpose, which you recommend?

Thanks,
Mircam

Arduino has been used by many people for this purpose - check this section for posts by draythomp to see some examples. The arduino is single threaded so it won't actually do things truly simultaneously, but it is fast enough that for domotics purposes, you won't notice. The model you choose will of course depend on how many things you want to sense/control.
