treasureFinder

Inspiration

The #1 goal of a pirate is to search for buried treasure, and this device does just that.

What it does

The device uses a hall effect sensor, a passive buzzer, LEDs, a potentiometer, an accelerameter//gyroscope, and an OLED screen help pirates find buried treasure! The hall effect sensor detects a parallel magnetic field, and when the sensor detects this the blinking light pattern changes, the buzzer pattern changes, the user recieves a message on the OLED screen, and if the treasure is detected for long enough, the pirates theme begins to play on the buzzer.

How we built it

The project was built with Arduino hardware and programmed with Arduino IDE.

Challenges we ran into

I wanted to be able to find the distance that the treasure was at but I didn't have the right hall effect sensor to do that. I also wanted a sensitivity dial, but I ended up just simulating that with the analog values from the pot. I didn't end up getting the accelerameter//gyroscope to work properly to keep the tool paralell.

Accomplishments that we're proud of

I am proud that I got the project to work.

What we learned

With this project I learned a lot about the different arduino sensors

What's next for Treasure Finder

-implementing the accelerometer//gyroscope to help the user keep the toolhead parallel to the ground

-potentially upgrading the digital hall effect sensor to one that can receive and and output analog values

-working on the design of the device itself and the user interface with more buttons and features like more lights, more sounds, haptics, different modes, more data readouts to the user, etc. One mode I want to add is one that changes the

-add animations to the OLED display
