Automatic Voice Activated Door With Google Home

myminifactory

This is a set of models that I designed and printed to create a pulley system to automatically open and close my door through commands of my google home. I took the code and instructions found here: https://www.instructables.com/id/Control-Your-Projects-With-Google-Assistant-and-Ad/ full credit to them for that. I then adapted it and wired it up to a L298N motor driver, which connected to an old drill motor with chuck. The drill attachment going in the chuck then string or wire of any type looping around the mount then up to the pulleys which are held to the wall with hot glue and bearings in the pulleys then press fit into the wall mounts. Note: That depending on where you glue your pulleys then some additional angled pieces might be required between the wall mount and the actual wall (As can be seen in the top middle red pulley, how it is at approximately 30 degrees to the wall)
