Final Project Journal

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

Kids tablet

This project targets children with learning difficulties

It helps teach them to memorize colors in an easy and fun way

Where I send a question via mobile (Bluetooth)

Click on the red button

The child chooses the appropriate color from the buttons

and press it .

In the case of the correct answer, three red lights are ON

A colored rose rotates in half of the tablet

Where there are three requests in three colors

Red - green - blue

When choosing the wrong color, we hear the wrong sound from the buzzer .

The purpose of the project is to produce a simple game for children to use

And it has even a small part of thinking about the method of operation

And part of getting attention is doing something and getting a reaction

The reason for my interest is that I have two daughters who have learning difficulties

The source of inspiration is the tablet that children spend many hours using

I can replace it with this game.

I Installing and assembling parts with the joint feature

The picture on the left shows

The part with the Arduino slots

And the power entry circuit

An Arduino projection was made to make this hole

For the power, a circuit was made after measuring the connection with digital buckles

And the second photo

Described as assembling the entire fusion of identical and equal parts

and assembling Dc motor - Arduino Uno - Lcd screen

The joint connection was made by choosing a point in the middle of the end of the parts and connecting it to the other parts

I create components - components for each part of the project

The number of parts is 6 parts

And added components such as Arduino and motor

And neopixcel to make slots for screws accurately

And make a place to connect the Arduino

And another to connect the electricity transformer 9volts

Then I assembled the parts on the program and made sure they were correct

Save the file and convert to dxf files

To cut it on the laser cut

And I made a print part that is installed on the motor, the suction part

And I saved it as a MASH to use Cura, then print the file and save it to gcode

All files attached

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)

DXF Files

STL File

Video for Laser cutting

Video for 3d Printing

The fabriction process using Laser Cutting

and 3D Printing

After designing the model with Fusion program

and save the file as dxf

Files are placed on memory

And I made an import of the files on the RDworks program The parts were collected next to each other to save wood

And I set the machine to cut at a speed of 30 and the power from 50 to 60

It took about four minutes cutting

Video file attached

also

I took from Fusion the other design for 3D printing

and i saved as a mash file

Then use Cura and open it and adjust its measurements as ( infill 20 - Resolution 0.3 mm extra fast ) that cost one g and 5 min

A video file is attached

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)

Video

I used this components :

Arduino Uno
3 push button .
Buzzer .
Breadboard .
LCD Liquidcrystal i2c .
Jumpers .
Adaptor 9 V .
3 neopixcel led .
switche on / off
Dc motor
L298 N driver .

the Describe electronic circuit

I created the electronic circuit as follows:

I started with Arduino after uploading the code to it

Who will control all departments and orders

And I connected it positively and negatively on the breadboard that we use to connect all the other parts on it

To take the negative and the positive

there are Four input units were used

3 Push Buttons + Bluetooth module via mobile phone

And output units (screen - buzzer - 3 neopixcl - and a Dc motor with L298N Driver )

Then I send the value (1) from the mobile

The Bluetooth connected to the breadboard receives it

The Arduino commands the screen to display a message by pressing the red button

It appears on the screen and within three seconds

The person must press the correct red button

It happens that the three neopixcels light up in a red color

The motor works and rotates the shape of a flower clockwise for two seconds and counterclockwise for two seconds

When pressing an error input unit ex. the green button instead of the red one, we hear a beep (Buzzer)

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)

The smart device is powered through a power source

Adaptor 9 V = 2 A

All electronic circuit components

It only needs five volts, and the Arduino can give it what it needs

However, there is a DC motor that needs about 300 milliamps

This is a number that the Arduino does not cover

So we need another source of energy

A nine-volt transformer

inputs power to the L298 N driver And the motor is given

It gives electricity and ground to the five-volt Arduino

Also, at the same time, the Arduino controls the motor

The motor works efficiently in both directions .

Project Programming

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

Coding file *ino by IDE

Reserve a place worth one letter

And the definition of the three push buttons on arduino pins :

the Red pin 5 - the green pin 6 - blue pin 7

Buzzer in pin 9

Arduino motor definitions

To control the speed and direction of the DC motor

They are output units

Define the Buzzer an output unit

And the definition of push buttons as Input Pullup

Download LCD screen playback library

And the Neopixels playback library

And the definition of Benz pixels on the pin 2

and count of neopixel are 3

LCD screen operation command

and backlighting

Turn on the screen when entering a value

Run the first condition

When sending value (1) from bluetooth

The screen displays an order

(press the red button)

and witting for 3 second

If the red button is pressed

The answer becomes correct

So turn on the three neopixcel with the same red color

With the motor running by 150 speed

for two direction

else make buzzer for one second

the same things by sending values ( 2 and 3 ) with different color == Green and Blue

last code

waitfor four seconds

Then clear the screen

And close the neopixcel off

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)

VID20230322005606.mp4

All project units are integrated

Since the beginning of the design, I use separate components for each part

And add the internal components from Arduino, motor and others

Through the GrabCAD and also from files sent on the portal

Use the joint property

Installing and assembling parts with the joint feature

I also made holes for the internal components by projection

And make separate sketches for it

Then made an Extrud for it

The integration was tested several times, with errors corrected when any

And i will add at the challenges

The project is working fine and excellent

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?

No I did not

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?

challenged

It is after cutting the wood with a laser

I found that some parts have errors

The first part, because I'm on RDworks,

I moved the parts closer to each other

But this part has tab holes and it was not assembled

The holes are in the wrong place

The second part

It broke when assembling the wood by hand

the third part

It is that I found the openings of the internal components were accurate, and did not allow entry to the screen, for example

So I made The size larger than normal, one millimeter, so that the parts could fit in their place

Future Work

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

Change The color of wood

and choise the sheet wood 6mm

Add other ingredients

And make the screen write in Arabic

And add a game with numbers in addition to colors
