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, I wanted to create an educational geography game using a simple electrical circuit. The player matches a continent’s name with its location on the map. If the answer is correct, the LED lights up and the buzzer sounds. I care about this idea because it makes learning fun and interactive, especially for kids.

Tool Chain

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

software

Electronics

Material

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?

Tinker Cad design

I opened Tinker CAD and made a new design

. I dragged:

Buzer, which in Tinker Cad is called "Biezo"
resistor 330 Ohm
red LED
Power supply, and I set it at 5V
mini breadboard
slide switch

I made parallel electric circuit, to make the5V move in the buzzer and the LED too

Before stimulation

After stimulation

Preparation of cardboard

First, I cut the cardboard to make a box its dimensions 63.5*8*25.5 cm
I used paper to draw continents and color them
I write the names with a black marker
After that, I fixed the paper with adhesive glue in the right place
I detected the continent place with Galvanized nail

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?

wiring the circuit

I made the circuit and made sure to be right

the white wire connected between the +ve part of the buzzer and the slide switch
In the same column, I put the red wire (which is from the +ve terminal of the adaptor ) and put the resistor
The black wire is the -ve terminal of the adaptor
the brown wire connected between the the other pin off the slide switch and the ground

After that, I extended the LED with wires to put it in the right place

black wire in the negative
white wire in the positive

I used wires and crocodile wires to connect the name and place of the continent

. I connected one of the continents and its name with the same wire, so when I touch the correct name and place it would be a closed circuit, so the buzzer and the LED would work

I remove the place of the negative part of the power supply and put a spare wire

and didn't connect the negative part of the power supply so when the pins of the spare wire and the negative part of the power supply

so when the pins touch the name and the place of the right continent it will be closed circuit so the buzzer and the lamp will work

At the front of the box, I put the Rozita, which we connect to the power supply it
The black wire comes from the negative part of the power supply
the red part is the spare wire which I put in the place of the negative wire of the power supply in the breadboard

The final project

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?

After checking everything, suddenly the project didn't work, so I used an Avometer. I found that the LED didn't work, so I replaced it with another new one

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?

The crocodile wires weren't enough, so I used wires to connect between the place of the continent and its name

When I used the on/off switch, I connected it directly to the 5V. So when it was on, the wires heated up, and it didn't work. When I told the instructor, she told me that I had made a short circuit on the adaptor, so the on/off switch burned. I used a slide switch because it performs the same function.

Final Project

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

I tried to make the prototype useful and it worked. I learned to look for available alternatives.

WOW!

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