In this project, we built a remotely controled door lock, that can be controled using your fingerprint. Thanks to Adafruit IO, it was also really easy to connect the two parts of the project wirelessly.

You can now experiment with this project, and of course modify it at your convenience. You can for example replace the door lock by anything you want: a simple relay, or a PowerSwitch Tail Kit to control an electrical appliance.

You could also imagine controlling several devices at once in your home just by placing your finger on the sensor once. For example, you could have all the doors in your home connected to such a project, and locking them all at once.
