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)

The idea of week 7 is to make a project with 2 inputs (If some one is around, The door will be opened automatically) and (If we are at night, A specific lamp will be turned on).

I `ve always liked recycling and minimalist and also liked living a fancy life.

This inspired me to make a smart building that uses electricity only when we need it or when it is after sunset.

Tool Chain

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

For the Input

I used an ultrasonic sensor that detects if anyone around.

And the light sensor to detect when it is at night.

An Arduino as a brain

Arduino UNO

which reads a signal from the (sensor).

For the output

I used the LED, resistor, servo-motor, bread board and wires.

Bread board

Wires

LED

Servo-motor

Resistor

Arduino app.

to make a code that control the out put (red light and opening the door)

Card board, scissors, glue

That will allow me to make the design to put all the component inside.

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?

For Arduino App.

First, I used an Arduino Uno board to control the circuit.(brain)

I used an Ultrasonic sensor to detect the objects on a distance of 10 cm. or less (Input1)

and a light sensor so if we are at night it will turn on a specific lamp. (Input 2)

I put a servo-motor to open the door, if some one is around.(output1)

and also a Red LED that will make red illumination as an alert.(output2)

FIRST define :

trigger pin is no 6

Echo pin is number 10

Servo pin is number 9

we will use Cm as the measuring unit of distance

and the one that will calculate distance is no 10

Second Void:

We will specify the input and output

Finally Void Loop:

If the light sensor can`t detect any light (dark)

turn on the LED

If there is someone around the servo motor will move to open the door

( I used Chat-GPT for the code)

For searching in Chat-GPT (PROMPT)

I wrote: as an Arduino expert write a code for an Arduino that tern on a servo motor when somebody is near 10 cm or less and a code for a LED that will turn on at night.

then I tested the code on Arduino app.

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?

1-After saving the file of Arduino App The file in Arduino app.

2- Connect the Arduino to the lab-top using the USP cable.

3- Be sure you chose the right USB of Arduino and press upload.

How to connect wires?

The Arduino UNO Connection

The 5 Volts with a positive N in the bread-board

The ground with the negative N in the bread-board

The Sensor Connections

The Ultra-Sonic Sensor:

VCC to the positive on the bread-board

Triger to 6 on Arduino

Echo to 10 on Arduino

Ground to negative N in bread-board

The Light Sensor

VCC to the positive on the bread-board

D. to 7 on Arduino

Ground to negative N in bread-board

LED

The positive leg to 11 on Arduino

The negative leg to resistor to the negative N on bread-board

Servo-motor

The orange wire will be connected to 9 on Arduino

the red to the positive on bread-board

while the brown is to the negative on bread-board

Don`t worry if the LED didn`t work .

just check the codes and the wires and finally you have to be sure the sensor can detect enough light 😉

Community of Learning

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?

The problem:

I thought that the sensor didn`t work or the code

so I checked every thing even I asked Chat-Gpt.

after I asked the instructors and everyone that may help.

I remembered that my room have yellow low light not high white light. turning on the torch of the mobile solved every thing.

For shooting while I am using the same mobile I used another torch and finally everything is O.K. AL7.

Final Project

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

I think I am trying to ask myself questions that may help analyzing the problem.

Inst. Mahmoud told me that and it is working AL7.

WOW!

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

I like the team of interns so much.

Happy to have them really 🤩

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.

I bought more materials for making candles this week.

Can`t wait to make more girlish crafts🌷
