Inspiration
In the age of IoT, even the most advanced doorbell technology (Ring Video Doorbell) is hardly connected to the actual door lock. Though the video camera features are nice, it's not enough.
What it does
This is a proof of concept of a wireless door lock: It allows you to remotely lock and unlock your door using an Android app.
How we built it
We used an Arduino as the microcontroller for the servo motor, which is the model for the lock, and a hc05 Bluetooth module for the Arduino.
Challenges we ran into
Which the hc05 is a good chip, it's limited in its capabilities. Controlling the lock from too far away is simply not possible with Bluetooth, so we needed to limit our goals to the abilities of the hardware he had access to.
Accomplishments that we're proud of
We were able to get a working prototype which can be easily expanded and scaled using different technology. We had many ideas for this which we were not able to do, but we can in the future with different hardware.
What we learned
Coming in to PennApps, we were both unfamiliar with Android Studio and Arduino, but were able to learn how to use both over the course of this hackathon.
What's next for Wireless Lock
Rather than using Bluetooth, the future Wireless Lock can use the Cloud to receive messages that were sent from the mobile device. There will be features of adding users to a group and giving all of them access to open the lock. There will be encryption to mask the data that the device sends to verify that it is a registered device for the lock.
