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)

This week, we were assigned to build an electronic device that performs two actions using cardboard. I decided to fabricate a handheld metal detector game. A handheld metal detector is like a small wand that you hold in your hand to check if someone or something has hidden metal quickly. It is like a game metal detector. When it finds metal, it lets you know right away with a beep, light, or vibration. It also has a fun side; people often use it on the beach or in parks to search for hidden treasures like coins, jewelry, or small metal objects buried in the ground

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?

TinkerCad Project : LED, Buzzer and Motor

What the circuit does :

In this project, I built a simple circuit that runs on a 5 volts battery. The idea was to have three different outputs :

lights,
sound,
And mouvement, all controlled by a single push button.

Here's how it works;

When I press the button, the red LED lights up,
The buzzer makes a sound
And the DC motor starts spinning , creating a little vibration.

All three happen at the same time, just by pressing one button. Everything is wired in parallel, so they all get the same voltage(5V), I used red wires for positive and black wires for ground, to keep the wiring neat and easy to follow.

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?

The circuit Process

c.mp4

I powered my project with a 5 V battery. The components I used were a green LED with a 320 Ω resistor, an active buzzer, and a Fan. I connected them all in parallel so each one received the same voltage and controlled by a one on/off switch. When I press the button, the green LED lights up, The buzzer makes a sound, and the fanstarts spinning , creating a little vibration.To keep the wiring clear, I used red wires for positive and orange wires for ground.

Cutting/Making cardboard Process

Starting preparation my measure

Cutting the cardboard

cut the fan's front face and it's window , then cut holes for the on/off switch and for Led/buzzer

Putting the fan on its square

Then making a place for ON/OFF switch

Finally putting the circuit in the cardboard

Final look

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?

I was trying to find out how can i share the work i did in tinkercad, after so many search, One of My top instructors Hala Gamal showed me how to share it during the session in lab saturday;

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

Once I put my circuit in the cardboard and turning on the push button, it didn't work at the first try so i went to my bed 😭saying to myself all of this hardwork went into nothing. But i remembered that it wasn't powered🤣, i got up hoping that this time will work and it worked Al hamdoullilah.

Final Project

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

Learning how to connect components in parallel and series using tinkercad gave me a stronger understanding of wiring that I can use in my final project.

Working with the motors in the Sumo Car project showed me how adding movement can make a design more dynamic.

It was exciting to see how a simple motor could completely change the way I think about building projects.

WOW!

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

This week, the most fascinating thing I learned was how to build an H-Bridge circuit to control DC motors, and I know it’s something I’ll always remember. I also learned how to connect eight push buttons on two big breadboards to control the two motors of an RC car. With those buttons, I could make the car go forward, backward, and even turn left or right. Seeing it all come together and actually controlling the car myself was exciting and really rewarding.
