Week 4 - 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)

in this week I learn basics of circuits and how to use the bread board then How to measure voltage in a circuit using an Avometer and ensure the connectivity in a circuit

the assignment in this week was to design, simulate, and build a simple electronic device that performs two actions.

I choose to design "Buzz Wire".

Buzz wire is a steady hand game that is well known to many as a table top amusement. Buzz wire is a challenging and competitive game where you are playing the number of touches against time. The player has to get the right balance between speed and skill in order to obtain the a successful score.

Tool Chain

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

we use Tinkercad Circuits to design and test our circuits

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 5V adaptor as it's suitable for the buzzer and LED then used a resistor to decrease LED voltage in order not to be damaged

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 use Tinkercad and design my circuit.

Circuit Components:

Power Supply (5 volt adaptor)
Switch
Resistor (250 ohm)
buzzer (5 volt)
LED (3 volt)
Small breadboard
A long wire to design the path
DC Jack to terminal block converter
Body (Cardboard)

My circuit prototype

I used cardboard to finish the Buzz Wire.

Then I started to play...

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 search on how RGB LED word and how "7-segment display" work. one of my team mates help me to write number 7 on the "7-segment display" component.

after I understand how "7-segment display" work, I suggest to my mates to but 7 buttons to control to show any number

I use TinkerCad to do the two exercises and I managed to power an RGB LED so that it lights up with a Purple Color, but when I try to build it I found there is some thing wrong in my RGB LED as it doesn't have a red color xD.

then I try to Power a "7-segment display", so that it shows the number Seven "7", and then I put 7 buttons to make the "7-segment display" show any number.

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?

for the first time to design RGB LED and "7-segment display" I didn't search on how they work, so in the first trial I burn "7-segment display" because I forget to put a resistor and the voltage was high on the "7-segment display".

then I searched and ask my instructor and my mates till I managed to do to correctly.

for the RGB LED the red color didn't work.

Final Project

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

in this week I had a better idea on how I will build my final project, I learn to design, simulate, and build my circuit.

also tinkercad will be very useful to simulate my circuit to avoid burn any component again xD.

WOW!

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

every thing in this week was very cool starting by learning tinkercad, through show a purple light on the RGB LED and write number 7 and all number on the "7-segment display"

But the coolest thing was the buzz wire, I really was happy when I managed to do it
