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

The purpose of my project to get some plants with good health and gain a lot of tomato .

A natural plant without any chemicals to increase growth or pesticides that are harmful to health.

This system helps produce healthy fruits at home, facilitates home cultivation in small spaces, and periodically monitors plant health to ensure proper growth.

In our current era, technology has become a major part of our lives, so I am thinking about how to use it to develop a smart farming system that serves the environment and helps everyone to farm at home smoothly. While browsing Facebook, I was inspired by a beautiful farming system for growing grapes, which plays a role in produce fruit and provide an attractive view of the roof, adding a beautiful touch and a refreshing vibe to the roof.

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)

Arduino box design

the lower plate for hold the Arduino and relay and step down converter and bread board .

and the upper plate for holding lcd screen and on\off switch .

we have hole for the power source and wires of water level sensor , water pump which allocate in the tank

rec 1.mp4

rec 3.mp4

design the pvc pipe for the water planet based which planet would fit on it.

It is designed to fit the water dispenser so that it interlocks with it and secures it in place without moving, even during strong water pressure, and prevents water from escaping outside.

and have place for water level sensor

rec 2.mp4

water tank

it is designed to keep water and have 2 holes for the pipe and wires of sensor and pump

rec 4.mp4

water dispenser

the main purpose is distributing water to plants and creating an ideal water cycle without wasting resources

rec 5.mp4

water level sensor holder

To install the sensor in a location where it will give accurate and appropriate readings for the location in which it is placed.

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 work

open laser work and import files in dxf and choose cut from setting mount the wire between machine and laptop

choose the configurations

speed 300 and power 35

then press download

on machine press menu and choose the same file name you download previously then

press origin to make the laser start from the same point we mention it

press frame to see the size of design on real plate
press start to begin the cutting

VID_20250921_205153.mp4

prepare file for 3d printing

open ultimaker cura and open stl file and press slice

set configurations

standard quality 0.2mm

infill density 20%

generate support with structure tree

preview and save to the disk

then plugin the flash memory to laptop and press save to the disk

VID_20250924_142211.mp4

take the flash memory to the 3d printer insert it to machine then choose file and start printing

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)

the input the output

water level sensor buzzer - (green - yellow - red)

lcd screen 2*16 - water pump

RELAY & pump

positive of pump connect to NC of relay

negative pump connected to negative adaptor

last edit .mp4

leds wiring

every led have two sides one of them is shorter and connect to the ground and other connect to arduino pins

we need to add resistor 220 ohm because leds need 3.3v and arduino give 5v

red at pin number 4

yellow at pin number 3

green at pin number2

buzzer wiring

have two sides one of them is shorter and connect to the ground and other connect to Arduino pins

the positive side connect to A1

lcd screen

connect vcc to positive sign of bread board

and grd to ground or negative sign of bread board

SDA from lcd to pin number A4

SCL from lcd to pin number A5

on\off switch

A switch with three -legs, the middle one is connected to the ground.

and other connected to pin number 9

power source of project

we use one power source (12v adaptor ) to Arduino and water pump

for arduino we use step down converter wire with grd and Vin

for pump we connect negative sides each other and the positive wire of adaptor with common relay

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)

Electronics

adaptor 12v for pump& step down converter give 5v for arduino

resistor 330 ohm

buzzer need 5v

bread bord

arduino uno

red , green , yellow led 3.3v

water level sensor

water pump i need 12v for my water pump to make the water reach high up to 50 cm and go through water dispenser to reach the planets

relay

step down converter

arduino wires

wires and jumpers

Tools & gadgets

m3 screw

wooden plates

3d printer filaments

black electrical tapp

drill

screw driver

Equipment

pvc pipe

jar 15cm diameter and 25 height

Project Programming

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

include libraries from tools > manage libraries > search and install

we have two main functions

" void setup " & " void loop "

first we need to define every component to arduino pins

and initialize values

at void setup

set sensor as input

and buzzer , leds and motor as output

at void loop

make condition for controlling the pump when no water using relay

and the red led light up and buzzer make high sound

when sensor reads high level of water the green led light up and the pump workig

make manual switch for normal control

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)

VID_20250923_231340.mp4

sensor reads and buzzer react

when the level of water is low or there is no water the buzzer give high sound and red led light up and the lcd give empty .

when sensor get in the water with specific level give high level and lcd give high level and green led light up

VID_20250923_231553.mp4

how pump works

the water have continues flow in normal state when high level of water sesnor read

but when the tank have low level of water the pump stop working or the user stop the pump using the on \ off switch

VN20250930_184101.mp4

testing water pump

it works when the water level sensor reads high level of water and stops when low or press off switch

VID-20250928-WA0014.mp4

the final shape

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?

my instructor Hazem give me advice about adding on \ off switch for the project for user to control the pump and simple usage

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?

problem

i stuck with wiring the power source with Arduino and pump and same time when we have differences between voltage the Arduino need 9v and component 5v and 3.3v and pump need 12v

solution

so we use step down converter to Arduino that make Arduino safe from converting the higher voltage into heat or damage Arduino with continuous work

Future Work

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

Adding an elegant touch to the project and also designing a pipe holder.

to make it stand up in 90 degree using 3d printing
