Week 5 - 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)

Alarm System

We are always exposed to disasters, so he must always take care, so I decided this week's assignment project will be about protection.

so this assignment will be a mini alarm system.

and week's assignment was to make a simple electronic device that performs 2 actions.

when there is a fire, the alarm and fans are turned on

to help the people around

Tool Chain

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

First of all, I used tinkercad to make a circuit and check it before doing it in real.


Electronics Components:

  • Breadboard

  • on/off switch

  • Buzzer

  • Red Led

  • Jumper wires

  • Crocodile wires

  • 5 Volt adapter

  • Cardboard

  • White paper

  • Glue

  • 5V Fan

  • Push Button


Full Electronics Kit

cardboard tools:

  • Scissors

  • ruler

  • pencil

  • cutter

  • glue

  • tape

  • A4 paper

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?

I used a 5-volt adapter to power my circuit because it is more than enough to power all the components in my circuit.

tinkercad simulation

I started by using tinkercad to simulate my circuit and make sure that everything will be ok, I used a 5 Volt power, Breadboard, red LED, Buzzer, push button, Switch, and some wires.


When I press the push button, the buzzer beeps, and the LED lights up

(The switch should be on)

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 drew the shape that I will cut on the cardboard using a pencil and a ruler.

Then I used scissors to cut out these shapes and assembled them together and wrapped them in white paper.

I made the circuit on a breadboard and then I designed a cardboard box according to its size and putted the wires inside it.

I opened some holes in the cardboard so I could put the circuit components in it like the fan, push button, on/off switch, and LED.

On the side of the box, I made a hole so that I could run the Arduino from it using 5v adapter.

After I designed all the circuits and it works I started to make the design the box of the alarm system so.

I opened 4 holes in the cardboard to get the LED, DC Fan, push button, and switch out of it.

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)


The LED light and buzzer were weak and the fan speed is also slow,


So I asked the instructor about this problem and he told me that the voltage is divided into the 3 components so it doesn't receive the required voltage to work perfectly, and to solve this problem I have to connect my circuit in parallel not series.


After connecting my circuit on parallel it worked as I want.

Final Project

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

I learned how to make a circuit with more than one component and apply that circuit to a simple project like a game or RC car I also got familiar with that H bridge circuit and what it could do or help me like turning on 4 push buttons each 2 together, and I think this tips will help me a lot in my final project.

WOW!

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

The last task of that week was to make an RC car in a group, my teammates Ahmed & Samir.

we started to make the 2 H bridges circuits then after we made it we started to make the car design on Fusion 360 software and we struggled a lot with the dimensions we imported the files on LsaerCAD and cut them on a laser machine but we didn't use some parts and after that, we started to assemble all the parts and before the hackathon, we tried to play the car to make sure that everything is good.

and then the hackathon begins and we got 1st place with my team EZ to win.
