My project idea is about helping the user (plant geek mainly:") to leave his plant safely while my device watering it rationally with the help of a moisture sensor when it reads the moisture percentage is below a certain level the water pump will start watering automatically from a water source (bottle) inside the device body.
The device enclosure is inspired by an animated character called BAYMAX which in the movie is a healthcare companion so, I made the same idea but as a plant companion.
The idea itself is inspired by my own interests as a plant lover and my need to leave my plants at home without how to water it hustle.

the second side is the same as the first one but without any holes.
For the BAYMAX front face, i downloaded a normal image of him ➡️ transformed it on INKSCAPE program into lines (SVG) ➡️ inserted it on FUSION 360.
Then on LASER WORKS I copied his features to be cut with the whole face.
The length of the face is 42cm.

Input components:
ON\OFF switch {to control the circuit electricity}
Pushbutton {when pressing a funny message will appear on LCD}
Moisture sensor.{ indicate the plant moisture level}
Action components
LCD {as an output for the switch and button press}
Water pump{ after the sensor reads the pump will start working}.

First I started the wiring of the moisture sensor
VCC ➡️ 5v (ARDUINO)
GND ➡️ GND (ARDUINO)
AO ➡️ A1
381847567_6851751381534821_6293461023657952958_n.mp4Second step wa connecting the water pump
-ve of pump ➡️-ve of power supply (9V)
+ve of pump ➡️NO of relay
we need relay here to control any voltage shortage between the Arduino and the pump
the input side of the relay is connected with:
IN➡️~6
GND➡️ARDUINO GND
VIN➡️+VE ARDUINO
the step before integrating all components together was testing the ON\OFF switch, LCD & Pushbutton in the circuit
on\off switch: one leg ➡️ +ve rail & second one ➡️ arduino pin
push button: one leg ➡️ -ve rail and the other ➡️ arduino
LCD: GND➡️-VE rail, VCC ➡️+ve rail, SDA➡️A4, SDL➡️A5

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)
Final wiring and power supply:
1) VIN (Arduino)➡️ +ve rail (breadboard)
GND➡️-ve rail (breadboard)
so, now one rail is -ve and the other will be supplied with 9v source and the VIN pin is on it
2) pushbutton:
one leg ➡️-ve rail
second leg➡️~8 (ARDUINO)
3) LCD:
GND➡️-ve rail
VCC➡️+ve rail
SDA➡️A4
SDL➡️A5
4) ON\OFF switch:
one leg➡️+ve rosetta
second leg➡️+ve rail
it is controlling the electricity of the whole circuit now
5) Relay:
NO➡️-ve side of pump
Co➡️-ve rail
IN➡️~2
GND➡️GND (breadboard)
VIN➡️+ve rail
6) Regulator: {to regulate voltage from the power supply (9v) to water pump (5v)}
9v rail➡️9v leg on regulator
GND(middle leg)➡️GND rail
5v leg➡️+ve side of water pump

6- Describe the code of your project. How did you program each function of the project?
What should happen in detail?
when pressing the on\off switch the device will turn on.(doesn`t need coding)
once the device is on a welcoming message will appear on the LCD saying "HI, I am your plant companion", and because it's a long sentence I distributed it into 2 sentences with 2 coding lines in 3,0 & in 0,1. also i wanted it to appear only one time at the start and to not be repeated so i wrote it in the void setup.
also I identified the pinMode of the pump in it so it will be read once as an OUTPUT.
in addition to the recent point i wrote the LCD backlight code in the void setup to light.
inside the void loop I wrote all the code lines i wanted to repeat which are :
the moisture percentage indicated by the sensor and the pushbutton state
The Conditions Needed
1- when the moisture sensor read percentage less than 50% the pump will start watering automatically.
2- when the pushbutton pressed anytime a funny message will appear on LCD for the user.
that1s why i used 2 if conditions to make 2 orders applicable.

if you had more time, what one thing you would change\do next in your project?
if you had more time, what one thing you would change\do next in your project?
- i think next time i will takecare of the spaces and dimensions more and maybe think about a new mechanism to make the water source bigger without making the device body itself bigger or make it a movable like hanged device and it takes its water supply from another place.

- also i can add a nice to have feature which is controlling the device by my mobile.
Overcoming Challenges
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?

Starting without making a prototype to imagine which design do i really need wasn`t a good idea, after that, i tried to make a small prototype just to imagine some connections.
made my first design without any T-Slots just tabs and normal slots took a bit of time to redraw it again
if someone want to do the same project i think the most important thing is taking time to draw and thinking of what they want to put and where as i forgot some components holes and made it after that with a driller and it wasn`t an easy way.
