Week 5 - Journal

Ideation

Our assignment for Week 5 involves designing, simulating and building a simple electronic device that performs two actions..

I chose to make a fridge with two different types of output components.

And here is a link of my inspiration.

Tool Chain

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

Here's a list of software, machines, and materials I used for the assignment:

Tinkercad software for simulating

on/off switch

RCA female

Avometer for troubleshooting

crocodiles

fan

7 segment

5V adaptor

330 ohm resistor

breadboard

jumpers

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 simulation Process:

In this project, I used two outputs (light) in 7 segments and (move) in the fan.
Get the power supply (5v - 2A) as the power source, I replaced the Breadboard with mini-Breadboard to be easy in hiding in the bottom of the juice bottle.

I used the (on/off) switch to run my fridge.
I chose to display -4 degree to be suitable for the temperature of the fridge and as the second output.
I used resistors 330 ohm for the 7 segments, connect all together as shown in the photo.

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 connected the 7 segments parallel with the adaptor by breadboard as simulation.

2. I connected the fan with the adaptor, and connected the on/off switch series with it

3. I connected the two circuits together in parallel, and replaced the breadboard with Mini breadboard to be easier in mounting and integration.

Demo of the circuit

4. I made the body of the fridge with juice bottle, then integrate the components and cover it with Schweppes can.

5. I started to finish the internal of it. and mounting the breadboard and all wires in the box at the top of the bottle.

Here is a demo of the functions of the fridge

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 going back to the instructor when I wanted to ask something like, 'Can I replace the fan with something else on Tinkercad?' or 'How can I make sure my project meets the requirements?' and so on. I was forgetting to add an on/off switch, and then I received advice from my instructor Hala to add it.

Here is my advice: this project requires patience, especially when facing problems. Always do troubleshooting, review your connections and polarity, and the problems will be solved.

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?

1. The fan didn't work initially because I connected it with resistor in series, and it worked fine when I connected it directly to the 5V power source.

2. It was challenging to mount the components on the cardboard due to the numerous wires, making the process complicated.

3. The 7-segment display didn't light up the entire number, so I performed troubleshooting and discovered that two LEDs were burnt out. Therefore, I rewired the connections to different LEDs by connecting them to the circuit in reverse, which allowed me to light up the required LEDs.

Final Project

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

This week, I learned how to make electrical circuits and how to troubleshoot your circuit to detect the problem, and how to simulate your circuit first.

I encountered some problems and learned from them, so I think I will use them effectively 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?

Besides the hands-on learning experience, I thoroughly enjoyed the journey, absorbing valuable tricks and gaining in this week.

Weekly Digest

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 made this RC Car for end of week session 😍🤩

and I loved it so much !!!!!!
