to Solve the problem of traditional education and provide information in an interactive and enjoyable manner.
I love teaching and seeing children enjoy education.
The idea came to me when I was visiting with the children at the Exploratory Center for science and technology.
I saw big educational exhibits so I decided to make a little DNA model.

I used fusion 360 to draw my design as its easy to use ,friendly interface and easy to modify the project on it .
Ultimaker cura software for slicing and preparing 3D designs to be printed.
I used Arduino C Text to write the code in Arduino software
I used fusion 360 to draw my design:
I drawn a circle with 50mm diameter and divided it into quarters.
I drawn a offset plane with 100mm length and drawn same circle in first step.
I repeated this step 3 times.
I drew two lines between opposite points to give a twisted shape.
I drew lines between the twisted lines.
Extrude all lines as pipe 1.5mm thick and 25mm diameter for main pipe, 1.5mm and 15mm for connected pipe.
For the box that containing electronic components
I drew a circle with 150mm diameter.
Extrude 55mm length.
Shell with inner thickness 3mm.
Download the components from Grab CAD and then insert them into your design to make holes to connect and organize the components within your design.
made holes for screws and opened for arduino cable .
Drew sketch on top to draw the box cover .
Drew circle with the same dimensions with the same holes for screws
Draw the position of the buttons.

on cura
for DNA
I scaled down the dimensions by about 50%.
layer height 0.3
wall thickness 0.8
wall line count 2
infill density 10
it take 2 hours and 27 g
The same setting for box and cover but with original dimensions
for printing:
Save files as g code to.
transfer files to SD card.
Enter SD card to printer.
Preheat the bed.
Unloading filaments.
loading your new threads until they reach the right color.
Choose your file from the SD card.
And start printing.

https://wiki.dfrobot.com/DFPlayer_Mini_SKU_DFR0299
This site helped me to DF player with arduino and speaker .
My circuit composed of 6 buttons, a DF player and speaker
Buttons have two branch one connect with arduino on on pins form 1 to 6 and other wire to the ground pin.
input: push button
When you press a certain button, a certain sound plays.
Action: audio file (mp3 file)
User Input: push buttons
Brain: Arduino UNO microcontroller: works as code carrier and microcontroller, the Arduino Uno takes orders through code
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)

define input (buttons)
#define pushButton1 1
#define pushButton2 2
#define pushButton3 3
#define pushButton4 4
#define pushButton5 5
#define pushButton6 6
then if condition to play the sound when push on buttons
if press push button one play mp3 file 1
and so on

In my first attempt at DNA design. I wanted to twist the double strand of DNA with servo motor, so I used flexible strands for printing, unfortunately the strands were not flexible.
So I designed a ready twisted design
Design needs a lot of support and it was a big problem because when you remove it the DNA may break down.
So I asked the specialist for help and suggested that we could reduce the intensity of the support so that we could remove it easily.
