Azimuthal Projection 3D Map Decoration X Folk Music Puzzle Game - Arduino

INTRODUCTION

The following page will instruct you how to create an Arduino project, which has two main functions—plain decoration with lighting and folk music puzzle game, that incorporates the fields of geography, geometry, maps, United Nations, and music all together in one. Building upon the structure of hexagons, the device portrays the world map in the Azimuthal Equidistant Projection, which is the form of map projection utilized by the United Nations (and its symbol).

When activating the decoration mode, the continents of the map would glow in different colors determined by random combinations of RGB values through the use of RGB LEDs.

The game mode, on the other hand, requires users to recognize the origin of folk music songs (selected by randomly generating numbers from 1 to 20) and put his/her answer's continental board into its corresponding position on the main wooden board within a set time (pre-set for 1 minute).

Step 1: Design the Board

You can directly download the attached file or follow the steps below.

Outlining the Map

Download a map outline from Google
1. Google "united nations logo"
2. Select "tools - size - large"
3. Download your most favorite image (the one used by this project: link) *Try not to select the ones with complicated lines overlapping with the continental lands*
Transfer the downloaded map into the printing version
1. Color the undesirable regions into white by using the paintbrush function in Adobe Photoshop
2. Export the file (JPEG)
3. Import the file into Adobe Illustrator and use the "image trace" function to trace the map
4. Export the file (dxf)

Adding the Hexagon Background

Import the dxf file into Rhino
Select the "polygon" function and key in "6" for the "NumSides" option
Key in "3.5" for the radius value
Draw 28 equal-sized hexagons
Export the file in 3dm

Step 2: Laser Cutting

Import the previously completed file to xxx.
Using the laser cutting machine, print out the main body on the wooden board and the continents on the acrylic boards (2 transparent & 1 semi-transparent) (videos are provided above)

Step 3: Build the Device

Boards After Laser Cutting

Acrylic Continents
1. Use the UV curable adhesives to glue each continent's three boards together (with the semi-transparent as the middle layer)
2. Use the UV light to shine on the glued regions in order to allow the glues to solidify
Wooden Board Foundation
1. Manually remove the small land regions stuck on the main wooden board
2. *If any part of the wooden board is broken, use the UV curable adhesives to glue them back*

Building the Base (Bottom Foundation of the Entire Device)

Find an adequate-sized cardboard box, with dimensions as close as 13*9*5.7 inch (33*23*14.5 cm)
Using the wooden board as the reference model, trace the continental parts onto the top surface of the box
Trace the bottom part of the buttons onto the top surface of the box, with each button centered within each traced continental parts
Use a blade to cut off the button parts by following the traces
Within the traced continental parts, use a blade to cut off short segments surrounding the button
Trace two more bottom parts of the button onto the right side of the box (try to align the traces with the same height)
Trace the LCD display board onto the right side of the box (above the two buttons in the previous step)
Use a blade to cut off the two button parts and the LCD part by following the traces in step 6 and 7

Step 4: Build the Circuits

Referring to the schematics above, build the circuit.

Note:

The resistors for the RGB LEDs and the ones of the buttons are different, LOOK CLEARLY!
Since the LCD Display Board above doesn't have the I2C model, it's not connected perfectly. (LCD Display Boards with I2C models only have to plug in four pins)
- Connect GNDs on the displayer and the Arduino board
- Connect the VCC on the displayer with the positive pins on the breadboard
- Connect the SDAs on the displayer and the Arduino board
- Connect the SCLs on the displayer and the Arduino board

Step 5: Upload the Code

The code for this project can be found here or below.

Every coding line has a side note explaining its purpose and function.

Note:

All the specific D pins can be changed and adjusted based on your circuit's layout
All the delayed seconds can be changed into different values, but DON'T DELETE them! (These delayed seconds allow the code to flow more logically. Without them, some parts of the code might not work!)
On line 24 (the introduction of the "for loop"), you can designate the number of repetition you would like the loop to run for (the original value is 5)
The RGB LEDs' color combination in each button's "if pressed" and "if not pressed" loops can be adjusted and customized. (Originally, the RGB LEDs would shine in green if pressed while they would shine in red if not pressed. You can change the values to have creative colors for answering RIGHT and WRONG)

Step 6: Finishing the Device

Open the cardboard box and put in the previously constructed circuits (including all elements, ex: three breadboards, the Arduino board, the portable charger)
Referring to the code and the traced continental parts on the top of the box, stuff the buttons into each of their corresponding positions
- *You may refer to the side notes behind the codes in order to ensure which pin's button is for which continent*
Stuff the two "function buttons" (map-deco of D10 and puzzle-game of D9) into each of the cut-parts on the right side of the box
Install the LCD display board into its cut part on the right side of the box
Open the box and ensure all the wires are connected properly to the boards
Stick the wooden board foundation to the top part of the box by using double-sided tape (make sure to align properly so the buttons can fit right into the cut-part of the wooden boards)
Use hot glue gun to fill in the small region parts (not the main continents)
