Week 5 - Journal

Ideation

My assignment's idea and inspiration for this week.

I've always wanted to make that game and play with it, so i decided this was going to be my assignment for this week

Tool Chain

The software/machines/materials I used in the assignment.

Tinkercad

Bread Board

Crocodile wires

Adaptor 9V

Buzzer

LED and resistor

Lamp small

In my project I used the small lamp provided in the kit, the small lamp can tolerate larde voltages so i used the 9V adaptor to power the project.

The buzzer can withstand up to 12 volts so does the lamp, so the 9 volts were sufficient.

In testing on the breadboard though, l used a small led with the buzzer and l had to put a resistance with it, l used the 5.3k Ohms resistor for fear that it can burn, but when calculated I found out that ccording to ohms law where V=IR, when V=9 volts, I= 20 mA then R=450ohm.

Design/Preparation Process

The design process of my assignment. How I used the tool or software to design my assignment before fabrication.

First step was to simulate the circuit on tinkercad.

I started to put the components I needed:

power supply, led, resistor, buzzer, ON/OFF switch, and another switch instead of the wire in the buzz wire game.

The power supply is connected to the ON/OFF switch and then connected to the wire which acts as a switch, then to the buzzer and led which are connected parallel.

(When the end that is connected to the power supply touches the wire connected to the buzzer, the buzzer and the led turn on)

Circuit Simulation

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 had to test the circuit on a bread board, by following the schematic and connecting the led to the resistor paralel to the buzzer.

It's working!!

Then I had to make the cardboard prototype for the game

Making the wire out of tin foil

cutting the cardboard and making room for the ON/OFF switch

making room for the lamp

wiring from the inside of the box

adding the buzzer and connecting components

Final result

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 the end of week session in the hackathon we had trouble in the H-Bridge circuit, nada and ahmed helped us alot and advised us to reconnect the circuit, it was simply that the wires get mixed together and sometimes get out of the breadboard, but it worked fine after assembling it again from the begining.

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?

The challenge for me this week was the wire of the game, I couldn't find a similar wire at home and I didn't know what to replace it with, I eventually remembered the tin foil at home and tested it and it worked perfectly.

Final Project

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

WOW!

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

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.
