Project Ideation

1- Tell us about the idea of your project. Why do you care about this? What were you inspired by? Include images and videos of similar projects

An educational toy to learn Childrens the musical tones through piano instrument.

Because I'm interested in educational games or toys, and I think it's the perfect way to deliver information to a child. because of the interaction. it makes unlimited conversation between the child and the educational content with joy and enthusiast.

There are a lot of studies about how important and how difficult to learn musical notes especially for Kids it effects really good in their growth.

Inspiration: (OTOTO) is a musical invention kit which allows anyone to quickly and easily create their own electronic musical instrument. With OTOTO you can unpack the kit and make anything from a drum kit of saucepans to origami that sing when touched.

Project Construction

2- Explain the CAD process of your project. How did you use the software to design your project? (List the softwares/tools/materials...etc that you used)

first i upload kits from fusion library i started with lcd screen

from

https://gallery.autodesk.com/fusion360/projects/56696/lcd-display-20x4

creating the first sketch start with the project tool I use on the LCD screen to make holes and create a rectangle for the screen then I

start taking dimensions from the push buttons and neo-pixels to sketch their holes and I used rectangler pattern to repeat them on a line

I used the dimension tool to define the dimensions between the components

then I used tools like circles, lines, and arches to create the toy's frame

I used the dimension tool and tangent relation

I used the extrude tool with a 3 mm thickness

Then create a sketch on the bottom of the top part to design the frame and the connection between the PLA and the top/bottom wooden parts

I used an offset tool with a 2mm thickness

Then I uploaded an on/off switch and

used the extrude tool with a 6.5 cm height

I create the T slots and join the switch with the rectangle frame on the wooden part

Create the T slots and use the project tool to create ports for Arduino on the wooden part

Creating tapes with a 3x30 mm

Creating holes for screws to make joint between PLA and wooden parts

Upload a push button and create a joint with the top part hole

Assembly

The final result

3- Explain the fabrication process of your project. How did you use the machine to fabricate your project? (List the softwares/tools/materials...etc that you used)

I used laser works to prepare the part for cutting
it was 30 for speed 50 for power

Cutting 30 for speed 50 for power and engraving 300 for speed 20 for power with deleting the over lapse

then I uploaded the file to the machine chose the file make an origin point and tracked the frame then start

Then it fitted in its place

I used Cura to prepare the 3d printing parts

20% for infill

0.2 layer hight

10% support density

0.8X2 walls

215-degree material

first I get the file on the memory card with a reader

then I change the filament and cut its edge with 45 degree

I choose to upload it on the machine to put the filament

then choose the file and run it

It's about 7 hours and 79g

Project Electronics & Power Management

4- Describe your electronic circuit. What are the input and action components? What is the function of each? How do the components integrate together to form your smart system? (List the softwares/tools/components...etc that you used)

I used

1 On/Off switch

4 push buttons

1 LCD 20x4

1 Arduino Uno

4 Neo pixels

When I push the button I hear music from the processing program

and see its musical scale on the LCD screen

When I play the musical button I hear a piece of music and I see its scale on the LCD screen then the neo pixel lights up with each tone to learn the kid its places

Finally,

There is an On/Off switch connected with the 5 V Pin

Then I tried to connect it to a board and Arduino with 10 push buttons on pins from 2 to 13

and I connect the neo pixels serial with each other

Then I take the ground and the 5 v pin finally

I connected the output pin from neo pixels to the A3 pin on The Arduino

5- What is your power source? How did you select the suitable power source for your project? (List the softwares/tools/components...etc that you used)

I use the USB cable as a data cable and because of the sound, it's coming from the laptop

9v as a power source

Project Programming

6- Describe the code of your project. How did you program each function of the project?

First, include

the libraries

for LCD I2C

for Neo pixels

get the address of the LCD(0X27)

Then define the Neo pin(A3)

define the number of the Neo pixels

(10)

now define variables

for buttons for counter

Then setup

serial and pixel begin

define the push button as INPUT_PULLUP

and initialize the LCD

turn on the backlight

Then setup

in the beginning, the LCD screen will give the kid instructions (like how to play)

so we will set the cursor and write

Void loop

in the beginning the neo pixels

turned off

now if the kid pushes button 1(La button) it will print the letter (a) on the serial monitor and print (La)

on the LCD screen then clear the screen

if the kid pushes button 2(Sol button) it will print the letter (b) on the serial monitor and print (Sol)

on the LCD screen then clear the screen

If I push the love button once it will give me (the first half of the love story music) and will show me the buttons with lights and will tell me its names on the LCD screen

so I can repeat it after easily

If I push the same button(the love button) again it will give me ( the second half of the love story music) and will show me the buttons with lights and will tell me its names on the LCD screen

so I can repeat it after easily

I used processing to get the piano sound from the laptop

First, we will import the minim library

and import processing serial

then define variables for each one

and create an object from a serial class

define a variable for the data we received from the serial port

Load tones

define the Arduino port (9600)

We write this to make sure don't do anything except if data is available

This is mean if data isn't null print the value coming from Arduino

If the value = letter(a)

play the song (40)

Project Integration & Testing

7- Demonstrate with text and visuals how did you integrate the project’s modules together? What are the testing results? (Include a Demo video separately, showing a proof of functionality)

10 push buttons on pins from 2 to 13 /ground

and I connect the neo pixels module serial

with each other

then I take the ground and the 5 v pin finally

I connected the output pin from neo pixels to the A3 pin on The Arduino

first, connect the LCD i2c module then connect

the SCL on A5 pin

The SDA on A4 pin

and VCC with the 5 v pin

finally, ground

Sharing & Collaboration

8- Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

When the kid pushes the button the neo pixels light up 🔳

because the neo pixels light up just when the kid is pushing the pieces of music not the single tone.

and I helped them to solve problems after the fabrication

Overcoming Challenges

9- When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?

There was a problem with controlling each neo pixel individually with the adafruit library

The solution

to makeing it easy to control with adafruit library

First

pixels.setPixelColor(0, pixels.Color(0, 0, 150)); //0 IS the neo number in the serial connection so if I want to control them I'll call them as its position on the serial connection

pixels.show();

delay(700);

pixels.setPixelColor(6, pixels.Color(0, 0, 0)); // if I want the neo to get off I have to make its color (0,0,0) and then show them

pixels.show();

The LCD screen holes after fabrication it was a little bit narrow

The solution

I sand it with files

Too many jumpers so

The solution

I connected the neo pixels serial to decrease the jumpers

and I get a smaller breadboard

Future Work

10- If you had more time, what is one thing you would change/ Do next in your project?

I'll make LCD screen more interactive with the kid

The LCD screen will guide him in detail about the musical note

and tell him if he doing great with more musical pieces and buttons
