Fusion 360 (2d Sketches)
Creating a component for each side of the design.
Design the suitable points for T-slots on each side.
Placing the LCD by detecting the proper side and I added 2 small opening below the LCD to add 2 LEDs. I used Varner calliper to find the external circumference of the LED which is 4.8 mm.
In the Arduino side I left places for USB port, power sources of both Arduino and adaptor and finally for the On/Off switch.

Laser cutting process
Converting all sides on Fusion 360 to DXF files.
Make a final check on the RDWorks program to follow all lines are properly selected and closed to be cut or engraved by laser.
set black lines for laser cut with power 30 and speed 55.
Red lines for engraved shapes at the top and on left side of the design at power 20 and speed 300.
I made all drawings to be closed together to save time and energy during laser cutting process, in addition to check that all lines are single lines without duplicaation.

software tools
for design I used Fusion 360
for Circuit I used Tinker Cad
For Coding I used Arduino IDE (Explained in programming section in more details)
Circuit on TinkerCad
Power source is 9 volt wall adaptor as it is recommended to power Arduino with 9 Volts.
Selecting the suitable power source according to the components in the project.
LCD is powered by 5v via VCC.
Both sensors DHT 11 & Moisture are powered by 5V
Pump is powered by 5 V
2 LEDs are powered by less than 5 volts but I used 2 resistors each one has 220 Ohm value.

Soft ware fabrication (Coding)
a- Testing components
Testing each component alone because some components need a library .
Testing the moisture sensor to record the range of reading.
Testing the LCD I2C library.
Testing water pump
Testing DHT 11 sensor to detect the temperature of the surrounding atmosphere of the plant.
Printing on serial monitor
b- Modification process
I modified some reading
Mapping Moisture sensor by specific values map(output_value, 550, 10, 0, 100);
Modify the cursor for LCD to start at (0,0).
Modify the DHT 11 temperature reading to give reading in Celsius in stead of Fahrenheit by using the conversion f = (t*1.8) +32;
Both f and t are variables where f returns reading in Fahrenheit and t returns reading in Celsius.
b- Run all code
Run all code to debug all errors.
Double check if there is any code with a logic error or text error.
Before void setup
Void setup
void loop
Void loop
The code starts as the following
Read the moisture from the soil, if the moisture = 0 or < 20 .
Allow the water pump to watery the plant and if the sensor reads > 50, the water pump stops to transfer water.
At the same time if the temperature returned by DHT 11 sensor is < 20 makes the Green Led to lit up and if the temperature is > 30 makes the Red Led to lit up.
All data returned by the both moisture and temperature sensors are clearly presented on the LCD.

Modification my design
The first design had some mistakes such as big size and the top of design was not suitable to place hinge and there was no suitable places for Arduino data, power and power source.
Second design
One of peer suggested to fix the left and right cap stone and to open it from its center , I found it good Idea and I already went through this modification.

Soft ware challenges
After adding the DHT 11 sensor to measure temperature in addition to the moisture sensor to measure moisture from the soil. I stuck to convert the temperature from Fahrenheit to Celsius degrees.
Solution
I googled the problem and then I found different forms to convert I have tried them until I got the proper one.
Hardware challenges
First challenge to design a completely closed design, but I found it is not practical as the plant will be placed at the top of the system which is not safe for the electronic components.
solution
I changed the design before the laser cut step to be a horizontal irrigation system instead of vertical one.

10- If you had more time, what is one thing you would change/ Do next in your project?
10- If you had more time, what is one thing you would change/ Do next in your project?
I would add a bluetooth module to control watering plant or even to stop pump from working according to the user's need.
I would add more moisture sensors to act as a multiple irrigation system.
