It plays musical notes and lights will be turn on depending on the notes being played.
Beacuse I like to play musics especially on a piano and was curious if arduino was able to make something similar. Another reason is that I will be able to bring the project home and connect it to my own arduino to have a mini size piano on my desk.

I have decided to make the it in a box shape so that it will be easy and fast to cut which helps to save time. Adding a LCD screen also allows the users to see the current note being played and adding neopixel helps make the product looks nicer

That side (red arrow) will sit nicely on the key holder (blue arrow) with a sponge/spring stick to it so there will be a bit of height for the key to pressed down.
1. I make the base,front and one side.
2. I create a new sketch on the side and front in order to draw out the tabs
3. Once the front and side tabs are drawn I copy and move them to the opposite sides since the dimension are the same.
4. Than I use the combine tool to cut and tabs.
5. After that I create a top piece with the dimension cut out for the input and output devices.
6. Lastly, I create a new sketch for each sid and project geometry all the sides so i can convert them to dxf and put them in inkscape to laser cut.
| Pieces | Sketch/Image |
|---|---|
| Base | 
The combine tool was used to cut the tabs of the base plate |
| Front and back |  
I decided to set the number of tabs to 5, in order to find the dimension of the tabs I use the formula e.g. length/ntabs_l (From the parameters above) |
| Side |  
For the sides I have also set the number of tabs to 5, in order to find the dimension of the tabs I use the formula e.g. width/ntabs_w (From the parameters above) |
| Top |  
For the top piece I had to measure the dimension of the LCD screen, Neopixel with 5 LED and the assembled piano tiles. After finding the dimension I will have to decide where is the best place to put the devices. |
I use Ultimaker Cura to slice the pieces and check the timing. To able to use Ultimaker Cura I need to convert it into Stl format first.
Go to files > Export > file type : stl > save in the folder you want
| Setting | Infomation |
|---|---|
| Layer height | 0.25mm |
| Infill Density | 10% |
| Infill Pattern | Grid |
| Speed | 80mm/s |
| Support | Yes |
| Build Plate Adhesion | Skirt |
After multiple slicing and check which takes the shortest time to print, I have concluded that printing the all the white tiles together and printing the key holder and black tiles together is faster.
After slicing we can finally start with the printing
Below is a short clip of the white tiles being printed
Black tiles and key holder
Below is a short clip of the black tiles being printed
I converted the fusion360 drawing of the box into inkscape by creating a new sketch on each profile and save it as DXF
Than I transfer the dxf into inkscape
Open inkscape and go to files > import > insert dxf file
To change the canvas size fo to File > Document Properties
When laser cutting I had to try to make full use of the used pieces to recycle them so that it will not go to waste.

One interesting factor this prouct gives is that if the user do not want to play musical notes he/she can change it so that it can play music. Hence this can turn into a 2 in 1 product.
Below is a code that includes songs like:
1. Starwars
2. Pirate of the caribbean
3. unravel
The user can press the middle button to stop the music and change song.

First I assemble all the tiles into the keyholder.
I had to slot a sponge between the white and black tiles so it will not touch each other. (Blue arrows)
Than I put the arduino board and connect the circuit.
| Color | What is it for? |
|---|---|
| Blue | Buzzer: to play the notes when push button is pressed |
| Red | Push button : Act as my input device |
| Green | 1k ohm resistor for the neopixel |
| Purple | Resistor for push button (560ohm and 330ohm) |
I first do the testing of all the components together than put them into the box.
After testing, I put the arduino board with the input/output devices in the box and secure the base of the arduino board with bluetacks and place piano tiles ontop of the push buttons
I added the LCD screen neopixel than start doing wire management.
I first use masking tape to tape the wires together than use clear tape after that to secure it better
Additional program that I made
The stop button function , by pressing the center white piece
Piano_keys : Main Program
Music : Additional Program
