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)

The Week of Electronics says Hello!

Well, this week highlights electronics, yeah!

Do you have a voltage and LED? Then you can emit light!

But what about resistance, do you want to use it too? Let's figure out how we do this …

This week focused on how to be familiar with electronics, so the first step was to identify the fundamentals like the name of each component, and what its functions and how it can work?

And then I went on a trip with some of the kit electronics i received like LED, Resistance, Puzzer, Mini breadboard, 5V & 7V Adapter, dc motor, fan and an Avometer.

The next step was to start putting some of these ingredients together in an electric circuit using a mini breadboard and a 5 volt adapter.

There are many forms / components of electrical circuit can be done from the Kit Electronics I mentioned before.

So, Let me ask a question .. Was it fun and easy to do? Says yes? .. Good, then let's try to do the circuits / objectives more difficult with these electronics and may we add some new ingredients to the previous one such as the Avometer, RGP LED and 7 segment display.

Let us do not forget that I have to simulate online the circle using a tool / software called TinkerCad. Stay informed!

This week I did two exercises, the first was "Power an RGB LED so that it lights up with a Purple Color. I will simulate our circuit on TinkerCad and build it via connections on a breadboard".

And the second one was "Power a 7-segment display, so that it shows the number Seven "7". Also, I will simulate our circuit on TinkerCad and build it via connections on a breadboard"

You may want to watch the following videos to see how it works!

Also, do not forget to check the Assignment Design Files for the simulation of Powering a 7-segment display on TinkerCad in the end of this paper!

That's what I did for the assignment this week, yeah!!

Have you started to visualize it now?

And let me tell you this... It was an unexpected result that I got!

Let me tell you the story behind it...

It was a free day to spend more time with the Kit Electronics I received this week. It was the only day I had this week before the deadline. So, I took this opportunity to dig deeper without any stress/pressure on myself and have some fun or let me honestly say I have some free trials some of which are mirrored on tutorials/ Hands-on, Minds-on activities and some not.

So, having gained some experience with how to use the tools I own for different ways/purposes of use "I will do more elaborative statement on it in the following questions, stay informed!", I was encouraged to do random free trials using the circuit with LED, Jumper wires, Crocodile wires, resistance, puzzer, on/off switch, breadboard and a 9v adapter then got the result shown in the ambulance simulator video, Keep amazed!

It was an interesting trial and result I got, so I needed to check or simulate the circuit with a different tool / software called Tinker Cad and started connecting the circuit to the required electronics I used on the real breadboard. Hence the result was almost as expected and resulted from a real circuit.

Tool Chain

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

I used ingredients that include:

Breadboard
Jumper wires and crocodile wires
9V adapter
Two LED
Puzzer
Connecting terminals “electric roseta”
Two resistances
On/Off switch

and other cardboard materials, scissors, a pencil, and a glue gun to form a body that contains all the components inside of it and be like an ambulance car.

In addition, I used Tinker Cad software to build and simulate the circuit online with the same components I used on real breadboard such as piezo, a 9V power supply, LED, Resistance and On/Off switch to make sure what I did was correct.

Tinkerd Cad Software

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?

The ambulance car is an electrical circuit that includes two LEDs (red and yellow), an on/off switch, a puzzer to generate sound, connecting wires between components such as between the LED and the resistance, the positive and negative terminals, and crocodile wires to make the connection longer to use as easily as I did with on/off switch, two resistances to reduce the current going through the LED to make sure it won't burn out, breadboard to share space with all components linked together in a circuit and a 9V adapter as I used two of LEDs, two of resistances and puzzer so, I needed a 9 volt adapter to efficiently perform the required objective of the ambulance simulation.

In addition, there was cardboard from the supermarket, scissors, a pencil, and a glue gun to form a shape with the ingredients inside.

Regarding the software I used in this station it was Tinker Cad where I built the circuit using the same components I used to test and simulate the trials I did and get to the result I want.

Simulation Circuit using ON/OFF Switch

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 first started connecting all the components together, keep in mind that the negative terminal resistance must be with the positive terminal LED to keep the LED from not burning, as we know the resistance reduces the pass current to About 2A for the LED so the resistance bears approximately 3 amps.

Then I tried to run the circuit for that level of LED and resistors connected and it worked through a 5V transformer, and the light came out.

Then I started trying to duplicate the previous step by adding an LED and another resistance, then I connected the puzzer to the positive and negative terminals of the breadboard and tried to turn on the whole circuit and it worked, yes!

Now, it's time to connect the ON/OFF switch to both ends of the breadboard but with a 9v adapter to efficiently power and perform the ambulance simulation objective according to the number of LED and the resistance connected and the puzzer as well. "If I used a 5v adapter it will also turn on the circuit but won't give me the ambulance simulator I want, so I used a 9v adapter with two LEDs connected and resistances plus a puzzer". The ON/OFF switch works in the same line of work with the other components to be viable to control the whole circuit, then I tried connecting the switch to turn the circuit back on and what I figure out is a simulation of an ambulance you can watch the following video!

Now it's time for a cartoon step ..

At first, I needed to make an adjustable shape out of the cardboard I had brought from a nearby supermarket and start using the scissors tool, pencil, and glue gun to get the desired shape of the circle and components.

Next, I inserted the circuit with the components and attached them together to start the circuit again and it worked! It was a pleasant moment for me.

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?

Definitely! I asked for feedback and some of my colleagues were amazed at the result I got; it wasn't dependent on any resources. It's just daring trials gave me that simulation of an ambulance/emergency.

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?

I went back to the tutorials to check what I missed and how to get out of it. They were magic tutorials that focused on some tips & tricks that I needed to remember while working on my trials whether on real/visual breadboard or through Tinker Cad software.

At some point, I found that it might be best to review some of the tutorials that related to connections of components together to make sure I'm doing things the right way.

If others want to work on the same assignment, they may want to focus while plugging in the components on the breadboard and cutting off the power after each stop while they work on the connections. Turning on the power while building the connections may cause the LED to burn out or something else due to unnoticed wiring errors.

Final Project

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

I will use this Knowledge to build and operate the electrical circuit of the graduation project "Interactive Desk Lamp" and by installing the various components and integrating them with the rest of the 3D-printed parts and others made by a Laser Cutting machine.

WOW!

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

One of our "Hands-on-Minds on" activities this week was building an RC car using Cardboard, so I and my teammate started to use a breadboard first to create a circuit with push buttons, jumper wires, crocodile wires, a 5v adapter, wheels and two DC motor.

Next was the cardboard step, so we started using scissors, a glue gun and a pencil to form a shape that contains the electrical circuit for the remote control and the two wheels with the DC motors.

In the end, we used a battery instead of the adapter and had free space to walk the car, yep! You may want to watch the next video to stay informed!

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 Amazing HACKATHON Day and The RC Car, which is called Barq Bensine, yup!

Are you ready to start the competition? … To victory, yeah!!

The hackathon was as follows:

The first stage is that the participants are divided into teams and choose their own name.

The second stage is for each team to start researching or visualizing the shape of the car they want to fabricate and customize it with a name as we called it Barq Bensine Car!

The third stage was for each team to start designing their own car on the Fusion 360 software and save the file in DXF format to adjust the rest of the settings related to laser cutting on the Laserworks program, save the final design in G-code format and upload it to the laser cutting machine to start the manufacturing process.

The fourth stage was the manufacture of the remote control and the beginning of the process of connecting components to the car, such as the battery, wheels, mini-breadboard and others via Jumper Wires, Crocodile Wires, and other gadgets to complete the connection process and complete the electrical circuit of the car and the remote control.

The last stage was to test the power of the RC Car by competing with other cars and I guess my team made progress on that, do you think?

Ready?

Welcome to my beautiful and first car I made with my team!
