Week 7- Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

Well this week assignment idea was inspired from my sisters as they always come and take my clothes without my permission and even without me noticing it🙄, so I decided to make an alarm system for my wardrobe to let me notice that they opened my wardrobe and this will make them runaway before I come and catch them red-handed.😁

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Software & Sites

Tinkercad

Tinkercad is a free, web-based application that allows users to create 3D models, electronic circuits, and code blocks in an easy-to-use, beginner-friendly interface. Used for simulation also.

Arduino IDE

Arduino software system used to check and write the code for arduino then upload it on arduino board.

Arduino project hub

used for getting the assignment idea from it

Materials & tools

Tools for the circuit on Tinkercad

I used Arduino uno, breadboard, LCD i2c, IR sensor and photoresistor sensor

(Used the same tools for the physical circuit + jumber wires for connections.)

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

Preparation on tinkercad

Started by adding the components I need in my workspace and also available in my electronic kit.
Then connected each component to the breadboard and to specific pins on Arduino.
Using photoresistor sensor as an input. (ldr to analog pin A0)
Using IR sensor as 2nd input. (IR to digital pin 6)
Buzzer (pin 9) and LCD i2c screen (SDA to A4 & SCL to A5) as two outputs.

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

Code

The device is programmed as when the photoresistor sensor feels high level of light (when the wardrobe is opened) and when the IR sensor feels movement or difference in the Wardrobe environment, the buzzer will make sound and the LCD will show " Don't touch my clothes" message.

Used the Liquidcrstal i2c library for the screen.
used the threshold value that serves as a reference point to determine when an action should be triggered based on the input from the LDR sensor. , it helps decide whether the light level is considered "dark" or "light."

Trigger Condition:

If the sensor value (light level) is below the threshold and the IRvalue = High, it indicates that the environment is more bright than the set threshold, and the program will perform a specific action (sound the buzzer and display a message on).

Implementation

I added the components to the breadboard.
Connected each component to the Arduino as I designed in tinkercad.
Uploaded the code and tested the components.
Then added wire extension the the comment so I can mount it on the cardboard.
Used cardboard, cutter and glue gun to make the device closure.
Then tested the whole device and it worked.

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

Challenges:

After uploading the code to the Arduino the buzzer was triggered even though I did cover the sensor with my hand and I asked my instructor Ahmed Sami and he told me to try to use the sensor alone and see the outcome value on the serial monitor and I used this code from Arduino project hub to test my Photoresistor sensor.
After testing it I found out that when the sensor is in the dark it get the high values such as 1019 but when it sense high light is gets lower values such as 722 and that was odd cause normally in the dark the values should be from 0 to 400, but this helped me to adjust the condition for the device as I got the average value for my room light which was approximately 750 so in the code I said when the sensor feels light bellow 750 (room light) the buzzer will make sound but above that (Dark) the buzzer and the screen won't work.

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

Will in this week I learned more about electronics and coding based on texting and more importantly I learned how to use and code the LCD screen cause its one of my project components.

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

Title of Media

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.
