I want to open my door by bluetooth. It's got an electric lock.
This is my project: I'll connect my Arduino and a relay to the transformator (12v) in parallel, so I can open my door with the interphone too. Arduino is activated, thank's to the bluetooth module, from an app I've already installed in my android.
My questione is: Could be this dangerous? Are there any problems? Thank's and sorry for my english!

Get us some diagrams, there are always problems, your English is good enough for me to understand you , so dont worry there.
Cheers Pete.
