Fun Factory Box
Fun Factory Box
The idea of my project is to create a Montessori busy box designed to engage and educate young children from 3 to 6 years. This project addresses the issue of young children being curious and often playing with dangerous items like switches, plugs, and fans and the issue of being stuck to screens and mobile phones. By providing a safe and stimulating alternative, the busy box allows children to satisfy their curiosity and learn through play which emphasize hands-on learning and exploration without the risk of injury. This busy board will include gears, buttons, lamp, buzzer, motor, and a Whack-a-Mole game, all controlled by Arduino. One of my dreams is to create my own business designing STEM kits and Montessori boxes for kids. I’m thrilled to make this first step with the Fun Factory Box and help children learn while having fun.

Fusion 360
Fusion 360
I used fusion 360 application to sketch the design of the box, and save the design as .dxf.
GrabCAD
GrabCAD
This app were used to download the components needed in the project in order to add it into fusion to the assemle the vitually to the design.
Laser work V6
Laser work V6
I used LaserWork V6 Application in order to prepare the .dxf prepared on fusion and save it to RLD. file.
UltiMaker Cura
UltiMaker Cura
I used UltiMaker Cura Application in order to prepare my. stl file for printing and save it as .gcode.
First Component: Top Panel
First Component: Top Panel
I started to measure the dimensions of the components needed in my project to draw it in Fusion, so as you can see in the left side for the whack -a -mole game it has the LCD Screen place, the buttons and the LED holders, on the right side you will find a rectangular frame for the x-o game, halogen lamp and switch, Dc -motor, servo motor and 2-potentiometers and the empty place is for the Gears.
i made new sketch fie creating the gears using Add in option in Fusion 360.
Second Component: bottom Panel
Second Component: bottom Panel
The bottom panel wasn't that hard like the top, just i drew the dimensions of the H-Bridge and download STEP File of the H-bridge from GrabCAD and joint it to the panel.
Third: Sides
Third: Sides
For the sides i decided to use the t-slots, and on the right side you can see 3-holes, 2 of them for the adapter terminals as my project needs 2-adapters and one hole for the buzzer.

El Malky ML149 CO2 Laser Cutter
El Malky ML149 CO2 Laser Cutter
This Laser cutter Machine used to emit a laser that can cut and engrave according to the settled power and speed.
Preparing for laser cutting:
Open LaserWork and Import the saved dxf files.
Select the parts needed to cut and make it black, while the parts needed to be scanned with Red
Adjust the power and speed of each.
Cut: Speed 40, Power 45
Scan: Speed 250, Power 30Save file as .RLD.
Turn on the machine from the green circular button.
Open Laser work from the PC connected to the machine , and open my .rld file.
Make sure that the power and speed of cut and scan are adjusted.
Make sure that the origin of software is correctly set with the machine.
Press download, so that the file will be downloaded to the machine.
Now, from the machine, press on File button., and select my file.
Put my plywood sheet in the desired place, where the nozzel is pointing to the sheet, make sure its fixed.
Move the nozzel to the desired place on the wood, the press origin to set it as the origin that i wanted.
Adjust the focus.
Press on frame button to see the area of cutting and make sure that its okay.
Close the door, and press start.

Fritzing
Fritzing
Using Fritzing app to build my own circuit virtually, as my circuit has a huge number of wires, so that helps me to make the circuit identified and clear for me.
Building the circuit:
Building the circuit:
My circuit includes:
*The Microcontroller: Arduino Nano.
*The power: two-adaptors 5V and 9V.
Whack-A-Mole Game: For this game i used 5-push buttons, one to start the game and four for playing, also i used 4-LEDs with different colors, and a LCD I2C Module to display the timer and the score, buzzer.
Controlling a Fan with potentiometer: For this part i used Hobby gear Dc Motor, H-bridge to control the speed of the moto, potentiometer.
Lamp: I used Relay, Halogen Lamp, and switch.
Steering wheel: I used servo motor and potentiometer.
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)

5 volts and 9 volts Adaptors
5 volts and 9 volts Adaptors
At the beginning i wanted to used 9volts battery and 4.5 volts battery instead of using adaptors but the instructors advised me to use adaptors.
5-volts adaptor:
5-volts adaptor:
Connected to the VIn of Arduino to power up Arduino.
9- volts adaptor:
9- volts adaptor:
Connected to the H-bridge, Relay and Halogen Lamp.
And common GND for all.

I started the project by trying the Whack-A-Mole circuit, making the circuit was simple but making the code from scratch wasn't that easy, so i searched for codes that may help me and found one suitable, so i start editing on it.
As i already tried controlling the motor speed with H-bridge and potentiometer in week 6 so i started integrating it with the Whack -a-mole circuit, after that i integrated the halogen lamp and relay as i tried them before in week 8 assignment, Finally i decided to add the steering wheel idea instead of the piano idea , as the number of pins in Arduino wasn't enough.
First i made the circuit in a simple box just to imagine the idea and make sure that everything can work together and then i redo it again in the wooden box.

My instructors are suggesting to use multithreading in the code, to avoid lagging or instability of actions happening, i still didn't try to search and try to do it but I'm planning to try it and see if it will make difference in my project.
Also adding the X-O Game instead of the Maze was the idea of my instructor Eman which i really loved and it makes the box more catchy for kids.

One of the challenges that i faced that some components in GrabCAD wasn't with the same dimensions that i had in real, that makes dimensions wasn't accurate, My instructor helped me be sharing some components and the other was measured by the caliper in the Lab.
Handling the wires in the box🙊, i tried as much as i can to make color code for the wires, but i wish i could learn how to make PCBs and create my own for this project 😂.
I used a propeller dxf design to be fixed on the motor but because the motor's shaft is not circular, it didn't work so i projected the shaft itself on fusion and save it as dxf and add it to the propeller instead of the circle.
Handling the powering of the servo motor, as first i connected it to the 5volts coming out of the Arduino, Instructor Abdel-Rahman asked me to try connecting it to the 5volts coming out of the H-bridge and it was really a great idea that makes the servo works better.

I would like to learn how to design a printed circuit board (PCB) as the wires problem will not exist and also this will make it an idea for real project and business to start.
