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

Bad habits is a beast feeding on our time, health and concentration.

"snoozzy" is a box helps to minimize the bad habits by lock the things inside for while to keep you free from things help that help strengthen these habits and does not make them unavailable all the time .

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)

For cad design first i draw this sketch, i set the dimensions with consideration off the components dimensions at my project, also the size of things i want to lock.

fusion main sketches:

Box Base sketch

front side sketch

Box Side sketch

Back Side Sketch

partition sketck

Box Lid sketch

Box Top sketch

fusion main sketches with components dimensions after importing them:

Box Top with Keypad, LCD,buzzer and led holder imported dimensions.

(here i made a rectangular for the wires of keypad to get in the box)

Back Side with ON/Off Switch imported dimensions.

Lid with door hings imported dimensions.

Front Side with lock cave imported dimensions

Side 1 with limited switch, Toggle switch and pushbutton imported dimensions

Side 2 with Arduino imported dimensions

At my project i have 2 parts will be printed using 3d printing machine so i made their sketches and bodies:

first patr is the solenoide lock holder.

I used the imported solenoid as a reference for me .

second part is lock cave.

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)

laser cutting:

first i export DXF. files from fusion, I used Rdworks to arrange the parts on the 30*50 sheet we have.

after fabrication i used bolts to get all parts together.

I used speed of 15 mm and power of 80 to cut.

for laser cutting i use plywood material, first i put the sheet, set origin, upload the RDworks file, track the frame, close the door and finally start the machine.

3D printing:

first i export STL. files from fusion, I used ULTIMAKER CURA to arrange the parts.

the two parts were 17g with infill 20, and resolution 0.15.

for 3D printing i use poly lactic acid, after uploading the stl. file at the machine i start the machine .

i used supports with the solenoid cave.

after fabrication i used bolts to get all parts together.

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)

my circuit consists of two modes

the first mode:

manual mode which gives the user the ability to open the solenoid manually using push button without any timers.

the second mode:

automatic mode at which the box opens only with the timer.

I used Toggle switch for switching between the two modes.

Note:

the both modes the box will open with limited switch and solenoid lock.

the first mode tinker-cad simulation :

note:

-the motor present solenoid and bush button present limit switch.

solenoid is connected with relay not connected directly with Arduino as shown.

the first mode tinker-cad simulation :

note:

-i used LCD 3*4 not 4*4 as shown at tinker-cad circuit.

- i upload a photo of 3*4 keypad connection.

-a bush button and toggle switch are added at my circuit.

my device consists of:

-Arduino UNO Board. (Brain).

-Micro Limit Switch. (Input).

- bush button (Input).

-Toggle switch (input).

-on/off switch (input).

-keypad(input)

-4*20 LCD with I2C module. (Output).

-5v Piezo Buzzer. (Output).

-led (output).

-solenoid lock (output).

*The device uses 9V adapter to operate.

components

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 choose the power source based on the power needed for the different components i am using:

Since, ..the 20*4 LCD powered from Arduino , solenoid needs 9v or 12 v it takes this power from relay module, and 5v buzzer. all of the used components are being powered using 9v adapter. it's enough to power all the components. Arduino will manage the power output to all the connected components.

-LCD, Relay module takes it power from Arduino.

-the ground of the circuit is the same of all circuit.

-Arduino is powered from 9v power supply, i give Arduino 9v through Vin pin.

9v adaptor

Project Programming

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

code of the project was a long and difficult process for me.

I started with the simplest mode which is mode 1: where i used limitswitch to close the solenoid and the push button to open it simply.

here the pseaudo code of this mode.

and this is the code.

note : i connected the solenoid using relay module since i want to control the relay using arduino also to provide the needed power for the solenoid.

limit switch connected with arduino with pin and another pin at negative of the power supply.

bush button the same like limit switch.

mode 1 pseudo code

then i started at mode 2 with mode 1,

first i made the pseudo code using flowchart.

code description:

1- i include the library of LCD and keypad.

2- i start to write all integers i have.

3-at void setup i added the pins state .

4. mode 1 coding.

5.if function for locking and unlocking during mode 2.

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)

I was testing my circuit and code it on actual circuit ,it was not easy for me to make the circuit with all wires.

i get parts together first then i build the circuit.

-for enclosure i used the cross slots to get all parts together, after that i connect door hangs, loch and lock cave, limit switch and arduino using polts for switches and buttons there were a dimensioned circles for each one.

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?

yes, i ask my friends for feedback , one of them said this project will be useful more if we use it with kids, it will help with screen time and screen off.

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?

i did some mistakes related to the design but the biggest challenge for me was the space i designed for the circuit it was very small to my circuit size. which makes the wires broke and disconnect from board and Arduino several times during closing the sides of box with the base.

so if you will make this design you will need to make the areaof circuit bigger.

I solved this problem by using tap at the wires connections.

Future Work

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

if i have more time i would re-fabricate the box with bigger circuit space, also i will add a logo.
