I am doing security system for home , when you open the door , labview will require password to make sure of safety , 20 seconds time for entering password if the door opened and 20 second passed then system will alarm , if user does not enter password correctly , three trails are allowed , then system will alarm and all emergency lights inside the home will be on . All of those are working successfully with small switch and LED's to labview , but I could not find any safety in this system I want to add one feature , if the password correct , then the door will be opened automatically , is it doable ? I need DC motor ???? I am using doll home to be interfaced with LabVIEW. Sorry for inconvenience
