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's assignment is a simple electronic circuit.

I choose to do the wire buzz game because it reminds me of my childhood.

I found the idea on youtube.

Tool Chain

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

Tinkercad website for simulating the circuit before connecting hardware.

Cardboard for enclosure of the electronic components.

Breadboard for wiring all the components

LED for emitting red light when the loop closes.

Resistor 330 ohm to limit the current.

On/off switch for the whole circuit.

copper wire to make the loop.

Buzzer to generate sound when the loop closes.

Jumper wires & crocodile wires for connecting the components.

Adapter 5v for powering the circuit.

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?

At first I opened tinkercad to simulate the circuit before connecting the hardware components.

I connected the led and the buzzer in parallel after making sure of their polarity, and then connected a resistor with the led to limit the current.

Note that the slider is the ON/OFF switch for the whole circuit, while the push button represents the wire for the game.

Swipe to turn on the circuit.

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?

At first i cut the cardboard, to make the box for the components enclosure.

Then I connected the components as I did in the simulation, using a power adapter 5V since both led & buzzer require no more than 5V.

After that I tested the circuit before putting everything in the cardboard box.

Wires from inside and final circuit.

After that I took crocodile wires and female male jumpers to connect the switch, led & buzzer onto the box.

Then I had to make two sides for the box to hold the wire.

After that I tried to shape the wire as best as I could, and used tape to isolate the wire at the beginning and end of the wire.

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

At first after wiring everything, nothing works literally.

I didn't know which part was wrong and I had to troubleshoot each component separately to make sure that they're fine.

Until I measured the voltage from the 5V adapter and it wasn't even near 5V, I realized that the adapter was corrupted.

I replaced it at my next visit to the lab with a new one.

Final Project

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

My final project I would use push buttons and leds to control the piano keys.

WOW!

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

At the eow session we made a cool RC car (لاحق 2) which was designed on fusion 360 and each motor was controlled by push buttons using the concept of H-bridge.
