Materials Needed
Microcontroller:
ESP32 or Arduino board (e.g., ESP WROOM, TinyDuino).
GPS Module:
A GPS module such as the u-blox Neo-6M or ATGM336H for location tracking.
Power Supply:
A rechargeable battery (e.g., lithium polymer battery) to power the device.
Display (optional):
A small display (e.g., OLED or LCD) to show location data.
Storage:
MicroSD card module for logging data (optional).
Casing:
A portable enclosure to hold all components securely.
Connecting Wires:
Jumper wires for connections between components.
Software Tools:
Arduino IDE or similar software for programming the microcontroller.

Step by Step Instructions
1. Assemble the Components
Connect the GPS module to the microcontroller using the appropriate pins (TX, RX, power, and ground). For example, connect the GPS's TX pin to the RX pin on the ESP32.
If using a display, connect it according to its specifications.
If logging data, connect the microSD card module to the microcontroller.

3. Powering Up
Connect your battery to power the microcontroller and GPS module.
Ensure all connections are secure.
4. Testing
Power on your device and allow it to acquire GPS signals (this may take a few minutes).
Check if the device outputs correct latitude and longitude readings in the serial monitor of your IDE.

5. Data Logging (Optional)
If you want to log data, modify your code to write location data to a microSD card at regular intervals.
6. Enclosure
Place all components inside a portable enclosure for ease of use during treasure hunting or burial searches.
7. Field Use
Take your device outdoors in an area where you suspect treasures or burials may be located. Monitor the GPS readings and log them for later analysis.
