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)

Microwave oven

Assignment for this week is to Design, simulate, and build a simple electronic device that performs two actions ( emits light, makes noise or sound, and/or makes movement.

I choose to build a Microwave oven

I choose this project because :

Because I love to make stereoscopic things and it was also fun that they came out (light- move)
it suitable for this week assignment because I can design it with one motor . led , breadboard , some wires and cardboard and it will make two actions ( moves and emits lights).

Tool Chain

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

Software

-Tinkercad portal

to build and simulate the circuit online

The main components in the circuit

1- Breadboard and Jumpers to connect the component

3- 5V Adaptor

4- led

5- one resistors

5- DC motor

6- ON/OFF switch

and other cardboard materials, scissors, a pencil, cutter , paper

TinkerCad

Components

breadboard

Resistor 220 ohm

jumber Wires

Red Led

on/off switch

crocodile wires

DC Motor

ADapter 5v

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?

First Step

Design Circuits on Tinkercard

Design circuits on tinkercad using this component :

1- Breadboard and Jumpers to connect the component

3- 5V Adaptor

4- led

5- one resistors

5- DC motor

6- ON/OFF switch

The device is a microwave the input should be opening the switch and the outputs are lighting LED and Dc motor .

I used 5V adapter as all the components operate with 5V. The LED and the resistor, DC motor and switch all are operated with 5V.

I begin with open the tinkercad and drag and drop the component in the working area then built the circuit as shown in the image below.

circuits (OFF)

circuits (ON)

I added the motor to the circuit in parallel connection to ensure that the motor is in its best condition and tested it with the led.

Second Step

Design Circuits on Real and test it

I used 5V adapter as all the components operate with 5V. The LED and the resistor, DC motor and switch all are operated with 5V.

Parallel connection is often considered better than series connection in certain situations because it provides several advantages over series connection.

Overall, parallel connections are often preferred over series connections in situations where independent operation, equal voltage, lower resistance, and flexibility are desired. However, series connections can also be useful in some situations, such as when a specific voltage drop is desired across each component or when there are space constraints. The choice between series and parallel connections ultimately depends on the specific requirements of the circuit and the components being used.

Video of Electric Circuit

I tested the functionality of the LED and the resistor and dc motor on the breadboard to make sure that jumper wires, LED, resistor, dc motor breadboard and the adaptor are working.

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?

Third Step

Design on Cardboard

Cutting paper using these measurements

body measurements

inside component measurements

Some pictures during execution

Finally

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)

I do not have experience with electrical circuits, so it took me time to train, but with time this difficulty will disappear , Also I did not know the sizes of the microphone and the way to implement it, so I used this video

Final Project

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

The project has a lot to do with the final project because it taught me a lot of skills that I will use when I work on the final project, now i know to design circuit on tinkercad and implementation on breadboard

WOW!

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

It was a very interesting week because I was able to design a product and operate it using electrical circuits

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.

on that week we have Activity to To implement task as a group of 3 , my group was with Mariam and Ahmed

the Activity was:

Car Controller Circuit: Build 2 H-bridge Controller Circuits

Then we played a collision game with cars and my team won
