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)

Rotating fan with a led

This week we were asked to build a circuit that gives 2 outputs.

So, I decided to build a circuit that consists of a fan and a led were they both work together once the switch is turned on.

Tool Chain

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

I used two tools, one for simulation which is Tinkercad and the other is the breadboard and the components.

I used two tools, one for simulation which is Tinkercad and the other is the breadboard and the components.

The components I used are:

1-Red LED

2- Resistor of 1 kohm

3-5V Adaptor

4- Male-Male wires

5-Mini Breadboard

6-On/off switch

7-Crocodile wires

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?

In the design, a 5V is supplied by the adaptor to the circuit, then one leg of the switch is connected t the +ve terminal of the voltage source and the other to on a leg if the limiting resistor, the other leg then is connected to the anode side of the led, after that, the cathode leg is connected to the -ve terminal of the voltage source, also the fan is connected in parallel to the series connection of the resistor and the led.

We used a 5 V source as we only need 5 V to operate the fan, so we connected in parallel with the series connection of both the led and the resistance not only the led for 2 reasons:

1- So that the resistance won't consume a part of the power (lets say voltage for easier illustration) so the fan will be supplied by a part of the voltage only not the 5 V as a whole.

2- As we know, in parallel connection all the branches have the same voltage, in this case if the fan and the led are connected in parallel without the limiting resistances being the branch of the led, the led will break down as it will be over loaded with a power that it can't bear

Simulation of the circuit

Implementing the circuit on the breadboard

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?

First, I cut the cardboard to form a cube, then I fixed the mini breadboard on it

After that, using the glue gun, I started to glue the sides of the cube until it was formed.

Then, I cutted a part in one of the cube sides in order to act as a port to the adaptor

On the mini-breadboard, I reconnected the same circuit again as that done on the normal size breadboard

I fixed the fan on the cube and the same for the led

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?

The circuit before modification

While designing the task of the RGB led we took this week, I had a mistake done in it, as I forgot to add a limiting resistors before the leds to prevent their damage, through the discussion with the instructor and the team they noticed this mistake and gave me a hint in order to put them.

I also have been active this week and took part in the extra session done on Saturday.

At the EOWeek session after finishing the car.

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?

In the simulation on tinkercad I didn't know from where I can get the fan, I thought about using a moto instead but I wanted to make sure that this will be okay, so I started to search on the internet on similar ideas and I found that the motor is actually used in different videos.

Final Project

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

I think that the most important progress that happened this week is that it is the first time we were asked to integrate two skills or knowledge fields we learnt through the past weeks. Through the past weeks, we were asked in each week to understand, practice a certain module and implement an idea related to it, this time we were asked to use each of the knowledge gained in the electronics module in addition to that of the low-fidelity prototyping that we took on our first week. I like this a lot and it leaves me with a good feeling that am on the right track of being able to implement a medium-fidelity prototype using the skills gained through the 10 weeks of the diploma.

WOW!

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

Overall I enjoyed this week a lot as it was full of activities.

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.

This a simple circuit that acts as a traffic light with displayed ads, a gate that opens and closes according to the state (green , drive ... etc) and a countdown for each color (state).
