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)

My project idea for this week is to build a device that generates both light and sound signals from a single power source. The device will produce a composite light by combining red and yellow LEDs. It will also include a buzzer that emits a tone, operated by a separate switch, so it can be controlled independently from the lights.

A key feature of this project is a control dial (potentiometer) that allows the user to adjust the intensity of the light and the volume of the sound. This makes the device versatile, as one can easily dim or brighten the light, and make the buzzer's tone softer or louder as needed.

the main inspiration for this was my love for old gadgets. I've always liked the simple, hands-on feel of turning a real knob to make something happen, whether it's dimming a light or just turning up the volume on an old radio.

Thinking about those classic radios, with their glowing dials and chunky controls, is what really sparked this idea. I wanted to build something that gives you that same satisfying, physical feeling of control, which is very different from just tapping on a screen.

Tool Chain

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

Softwares

Google

I used Google to search for ideas and to get visual information that helped me get inspiration and develop the concept.

Tinker Cad

I used Tinker cad to model and simulate my circuit and to test it before circuit building

Tools & Components

Tape

Glue gun

Scissors

Cutter

Wires

220 Ohm Resistance

Breadboard

Switch on/off

Yellow LED

Slide Switch

Buzzer

Red LED

5V Adapter

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?

As it is in the circuit diagram , we have two output components LEDs & Buzzer

As it is in the circuit diagram , in simulation circuit works with 5V power supply & in real built circuit circuit works with 5v adapter

Circuit wiring using resistants in series and circuit components in parallel

Circuit Simulation

A Simulated circle that was made in reality to perform same 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?

Development & preparation & project making

Number of 220 ohm resistors two protect the red and yellow LEDs

I used various Wires like male male and male female and female male

some wires were too long so I had to tape them together and make them shorter

After I prepared my wires it was time to connect them to LEDs

I connected resistances to the wires I shortened them

Then I connected the lights to the same wires I connected their resistances to them

It's now the final shape that I got and I have to power it to test it

I use breadboard and power supply with wires to supply LEDs with power

It's now that we we have checked that LEDs works properly

Male female wires to connect the led leg to the breadboard indirectly

There are other components that needs to be in the outer structure

but the breadboard is inside the structure so we use wires to extend the connection

Power rosette with On/Off switch

We use on off switch with the power supply wires to make a control switch which is necessary for the Circuit

Starting attaching taped wires to the breadboard

We attach wires and LEDs together

To finally get them assembled

We have our components and wires in the desired shape we had to the next step which is assembling

We assemble cardboard parts with our components and put each one on its place

We Finally get the shape collapsed and assembled together nearly for all parts .

The last shape of the project control interface with switches and control components

We start a assembling and fixing components inside the structure

A project that makes 2 variable outputs Lights (from red & yellow LEDs) & Sound from a buzzer that is controlled by switch , with On/Off switch to control full circuit

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?

Yes, I got help on cutting the cardboard and reframing it and gluing it together as I found it very difficult but I got help with the cutting and the framing was so easy after someone offered me help on cutting as I always didn't like the cardboard cutting as it was so difficult
Ideas I got from others were how to cut cardboard easily and how to reframe it with other pieces easily

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?

I Really had a big issue with the Wires to still connected as they always disconnected it was very annoying as when I got closer to the end of the project some wires were disconnected or cut off so I had to unplug the glued parts and check all the wires from start it was very annoying as they got disconnected many times
the solution was to tape them and tie them with the tape to fix them together and to tape them with the breadboard so they are not getting disconnected anymore

Final Project

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

Using tape to fix male and female wires together was a good idea that I learned from the issues and challenges that I have overcome through the weekly project

Fixing the main components is necessary this is something I learned and I would absolutely use and consider in the 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?

I learned how to connect series and parallel and have to make a specific circuits I also learned how to control circuit with buttons and switches through interactive activities that will absolutely fun like the hackathon

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.

In the hands on session and weak we had a competition in the hackathon we had to make fighting sumo cars that was absolutely enjoyable and funny it was some new experience that we had and it was very interesting and very challenging as they were already computations between cards and maybe we didn't have luck to win the first place but it was really fun
