This laser-cut base is designed to support the barn structure and provide ample space for housing the animals. Crafted from 1/4-inch wood, this sturdy foundation ensures stability and durability for your barnyard setup. Assemble the pieces with precision using wood glue for a secure fit, guaranteeing long-lasting performance.

This laser-cut design is tailored for the back panel of the first barnyard box, serving as the housing for the Arduino, breadboard, and wires. Crafted specifically for 1/8-inch wood, assemble it seamlessly with wood glue for durability and precision. Additionally, customize a cutout on the side of the box to accommodate the dimensions of your switch, enhancing accessibility and functionality.

Crafted from 1/4-inch wood, this laser-cut roof piece serves as a seamless connector between Barnyard Box #1 and Barnyard Box #2. Assemble with precision using wood glue for a secure and durable connection.

This set of laser-cut files is tailored for crafting eight doors to be installed within the eight columns of Barnyard Box #1. Precision-cut from 1/4-inch wood, these doors are designed for durability and seamless integration into your barnyard structure.

For an authentic barnyard aesthetic, I've included window cutouts to adorn each door, enhancing their visual appeal. Crafted from 1/8-inch wood, these laser-cut window pieces are perfectly sized to fit onto the doors, adding charm and character to your barnyard setup.

This 3D printed addition serves as an enhancement to the toy's barnyard aesthetic. Crafted with white 3D filament, this piece is designed to be affixed onto the windows of the barnyard roof.

I printed 32 cubes with my 3D printer to hold the magnets for the barn doors. Each door needs four cubes. I used super glue to attach magnets to the cubes and the doors. It's a simple way to make sure everything sticks together securely.

Glue together all the windows onto the doors.

1. Insert the micro SD card into the adapter.
2. Connect the micro SD adapter to your computer using a card reader.
3. Copy your sound files (in supported formats like MP3) onto the micro SD card.
4. Safely eject the micro SD card from your computer.
5. Insert the micro SD card back into the MP3 module.
6. Power on the MP3 module and your sound files should be ready to play.

This is the coding to set up for the arduino mega board.

Here's how you can connect the MP3 player to the Arduino board.

MP3 Player Setup:

1. Connect the VCC (power) pin of the MP3 player module to the 5V pin on the Arduino board.
2. Connect the GND (ground) pin of the MP3 player module to any GND pin on the Arduino board.
3. Connect the RX (receive) pin of the MP3 player module to digital pin 19 on the Arduino board.
4. Connect the TX (transmit) pin of the MP3 player module to digital pin 18 on the Arduino board.

Here's the configuration for connecting the photoresistors to the Arduino board. Integrate this setup with the MP3 setup, and repeat it eight times for comprehensive coverage.

Photoresistor Setup:

1. Connect one leg of the photoresistor to the 5V pin on the Arduino board.
2. Connect the other leg of the photoresistor to analog pin A0 on the Arduino.
3. Attach a 10k ohm resistor from the same leg of the photoresistor that is connected to the analog pin to the ground (GND) pin on the Arduino board.

Integration with MP3 Setup:

1. Incorporate the photoresistor setup into the existing circuitry of the MP3 setup.
2. Ensure that each of the eight setups has its own set of photoresistors connected to the Arduino board, following the same configuration described above.

This combined setup will enable the Arduino board to interact with the photoresistors while maintaining functionality with the MP3 components.

nstall one photoresistor for each barn door, positioning them strategically at the back of barnyard box #1. Utilize a drill to create appropriately sized holes in the wooden surface, ensuring unimpeded passage for the photoresistors' functionality. So then you are able to connect the wires to the photoresistors.

1. Strip the insulation off the wires of the 9V adapter and the switch.
2. Twist together the exposed wires of the adapter and the switch.
3. Apply solder to the twisted wires to create a secure connection.

Barnyard Box #2 serves as a dedicated storage space for all essential components including wiring, breadboard, Arduino, speaker, 9V battery, and the 9V adapter. To ensure stability and organization, I secured each item in place using command strips, preventing any movement or displacement.

Connect Barnyard Box #2 to Barnyard Box #1 by securely gluing them together. Once the bond is firm, affix the roof to both barnyard boxes, completing the assembly. This simple yet effective process ensures a sturdy and unified barnyard structure.
