Week 4

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you?

The assignment this week was to build a simple electronic device that performs two actions so I chose to build a buzz wire

Tool Chain

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

I used tinkercad to test the circuit

Also used breadboard, wires, crocodile wires, resistors220v, led lamps, buzzer, motor, on/off switch, and cardboard and an adabtor 5v

Design/Preparation Process

I learned how to use tinkercad to simulate the circuit

Then learned how the dc motor works and how to connect it with the power source

then i learned how the buzzer works

how the dc fan work

also learned about the bread board and how to control led brightness

exercise 1

I searched about the orientation of the rgb led then I simulated the circuit on tinkercad

I added the rgb to the bread board then connected the cathod with the resistor then connected the negative wire with it

also i connected the blue with the other wire an connected it with the red with a resistor to get the purble color

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 by testing the circuit on tinkercad

at first I connected the positive and the negative wires of the power supply to the breadboard

then I connected the positive one with the switch button and the negative side with a resistor and a negative side of the green led lamp

the other side of the switch i connected it with the positive side of the Buzzer, the motor, and the red led

i connected the negative of the red led with a resistor and the negative of the buzzer and the motor then I connected it with the negative of the power supply to see if the circuit works or not

and the circuit worked

then i made the circuit outside but i didn't connect the negative of the power supply with the negative of the components like I did on tinkercad but I connected each of them with a wire then connected these wires with the hand and the path of the buzz wire using crocodile wires

then I cut the cardboard and assembled the components on it and closed it with glue gun and now we have a buzz wire

the green led works when I open the switch and the red led works with the buzzer

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?

In this activity in the mid week session i couldn't understand how to control the rgb with potentiometer and my peer Ahmed Elnaggar explained to me how to control it

Also we worked together and made a car with dc motors as i mentioned below

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 had a proplem that i couldn't use the seven segment so the instructor explained it to me how it works so I could get the number seven on it

I couldn't make the dc motor works in to directions that I tried to achieve that without using the h bridge but it doesn't work and the wires became very warm so I waited till the instructor mego explained it to us and me and the team used it in the hackathon and it worked

Final Project

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

now i can build a vision of how the final project will be like that I learned how to build a circuit and how to build simple devices.

WOW!

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

i had no i idea of how to interact with electronics before this week I've never done something like that and here we are I build a buzz wire so the whole process is cool and i am really happy for what i learned

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.

me and my team amir and mariem made a cool car works with to dc motors an controlled with controller we made

unfortunately i didn't partisbate in design because i was late but i built the circuit with them
