Our team is from Mexico, and we know the dangers of being alone at Halloween night when kids go out to trick-or-treat, that's why we take in consideration those dangers and tried to make a hardware that ensures the safety of those who want to enjoy this day with safety.
What it does
It's a pumpkin pail that communicates via radio signals to a controller that can activate an alarm in the pumpkin. This is possible thanks to the FR24 modules of arduino, that has a maximum distance of 3 meters to connect, so every time the user with the pumpkin pail gets lost or gets out of the area, an alarm will sound causing led strips to flash on the pumpkin while a song plays at full volume.
How I built it
The three members of this team had previous knowledge about arduino and industrial modeling, so we decided to participate as a challenge, to explore the areas we already knew and improve with the practice.
Challenges I ran into
It became very difficult to found a way to connect 2 systems without the use of internet, first we thought about using a bluetooth system, but then we discovered the FR24 module of radio signals, so we preferred to make 2 hardwares and not just one, that leaded to the creation of this project.
Accomplishments that I'm proud of
We are really proud of the investigations we made, the hardest part wasn't trying to think about what could we do, but about how we are going to do it. We thought of using "radar" to make things easier, but we couldn't found a method to connect to the platform without the use of internet, thats when we thought about using another kind of wireless communication.
What I learned
We learned about searching from another perspective and mostly about the possibilities that arduinos can have and how we can use them.
What's next for The Pumpkin Transmitter
Improve, test and keep improving, Halloween is a very fun holiday, that is why we would like to continue improving the hardware so that in the future we can all enjoy this day with greater security.
