Week 6 - 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)

My assignment's idea for this week is creating a smart lighting system, when someone approaches the room, the led will light up.

I personally care about this idea because i believe it's an energy saving feature and it also saves the hassle of turning on the lights.

I was inspired from some smart lighting systems in the TV-shows where it shows that it only lighten up when someone is near.

Tool Chain

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

1-Software :

TinkerCad
Arduino Coding

2-Tools & materials:

Arduino UNO
Microwave Sensor
LED (White)
220 ohm Resistor
Mini breadboard
Female Jumpers
USB Cable

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?

First, I planned my circuit and tested it on tinkercad:

First, I picked the components, and I used the PIR Sensor instead of the Microwave sensor as it doesn't exist on the tinkercad.
I connected the led to the resistor.
I connected the led's end to digital pin 7 and the resister to the ground
I connected the PIR Sensor to (Digital Pin 8 - Voltage - Ground).
Then, I worked on the blocks.
I compared digital pin 8 to High using the math comparing feature.
Then I added an If condition, stating that if it's indeed high (meaning, if the sensor is sensing someone moving around), Pin 7 (LED) would be set to High, and after waiting for 5 seconds, it'll be turned off.
If Digital Pin 8 doesn't read high, the led won't turn on.
Finally, I tested the functionality of it by simulating the circuit as shown in the video.

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?

I tested my connection on the arduino:

First, I converted the blocks code to block and text, and I copied the text to the Arduino coding program.
I connected the female jumpers to the breadboard following exactly what I did on tinkercad.
I connected the USB to the arduino, and I uploaded the code to it.
I hovered around the microwave sensor and it did sense my movement and the led got turned on.

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)

I wanted to use the microwave sensor as it wasn'y used combined with the led before to test it out but it didn't exist on the tinkercad, so Amany told me to use the PIR instead.

Final Project

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

Coding with blocks and using arduino to act like the brain of the project.

WOW!

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

Coding using arduino blocks and then converting it to text, it felt like actually coding.

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.
