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 assignment's idea is device like the fire alarm.

When fire alarm button pressed the device starts to ring and the red light turns on.

I will do the same when I press the button the buzzer will start to work + the red LED.

Tool Chain

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

I used tinkercad to design and simulate my circuit before implementing it on the breadboard in order to avoid any mistakes while wiring.

I used cardboard as enclosure.

For the circuit I used:

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 stared new sketch on Tinkercad added breadboard, 5V power supply, buzzer, push button 220 Ohm resistor and LED.

After adding all components I started to allocate them on the breadboard.

I set power supply to 5V to power all components, resistor to 220 Ohm.

Final step was to wire all the components together.

I wired positive (color wire) from power supply to pushbutton and from the other leg of the pushbutton I extended the positive to the positive side of the pushbutton to the positive leg of the buzzer and another wire to the positive leg of the LED. (all positives are wired with red wire as shown on the pic).

I wired the negative of the power supply with the negative of the buzzer and another wire went to the resistor. (negatives are wired with black wire).

I added 220 Ohm resistor to the LED since it should receive only 2 volt and the power source was 5 Volt so, I calculated the needed resistor with Ohm's Law.

After I reviewed all components and wiring I pressed start simulate in order to make sure that the circuits works as it should be.

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 started the process by checking every component separately on the breadboard to make sure it works, then I added all components exactly as the tinkercad circuit I did before.

After that I started to make holes in my cardboard in order to put the components in its place.

I added all the components in its place, then started connecting the components to the breadboard.

I connected the DC adapter to the power and connected it to the rosetta and Zzzzzzzzzzz no the electricity didn't shock me, actually the circuit worked :D

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?

During the face to face session, the instructors split us into groups to do Car from scratch using H-bridge circuit.

My teammate was having a problem with the H-bridge.

I opened the video and explained the H-bridge to him and what to do and don't.

He understood it and we managed to finish our car before the time.

Since it was the first time for me to make a circuit I chose to make a vey simple circuit for this week's assignment.

While creating it I decided to try a new thing since I am learning by doing person.

I decided to add a push button for the buzzer and another one for the LED to try to simulate Morse code sending device since I know some information about it.

It did work and I managed to operate every component independently.

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?

~~Actually I got stuck in the enclosure since there were so many wires with some weight while the components are very small and not heavy.~~

~~I didn't want my box to be so big.~~

~~I learned from this mistake and wil try to find better way to wire with less and lighter wires.~~

I didn't like how my enclosure looks like so, I decided the re-do it again.

The first step I missed in previous enclosure was to try to use as less wires as I can so instead of using crocodiles to wire lamp and the buzzer I can use female to male jumper (I forgot about it first time :D)

I believe you can see the difference between first and second trial from the pictures.

Final Project

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

My project is mainly circuits and this weeks tough me how to wire and power components correctly in order to work probably and avoid wasting valuable material

WOW!

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

Building Sumo RC car was something amazing since we built it from scratch and designed the body.

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.

The Hands on Mind on activity at the beginning of week was amazing.

I loved it as I love electronics and wiring things together.
