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)

This week's assignment's idea is to build a simple electronic device that performs two actions.

I decided to make a buzz wire game: is a challenging and competitive game. The object of the game is to carefully move the wire wand loop along the copper wire “maze” without touching it. When the loop touches the wire, you will hear a “BUZZ”. The goal is to be fast and at the same time to be efficient, having the least amount of touches.

I choose it because I want something simple to start with it as it is my first time dealing with electronics.

so I searched on youtube to learn more and to get familiar with the parts and I found this youtu.be/KUGqEL6hgDM

TOOL CHAIN

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

Software

Tinkercad

Used to simulate electrical circuits and components, so I can calibrate circuit calculations,

The resistor calculator to calculate the ohm of a resistor, and before even going to the hardware step

TOOLS

5-volt adapter
Red led, buzzer
220-ohm resistor
on/off switch
wire

Tape
breadboard
jumper
crocodile wires
box

Materials

copper wire for the path.

white hard paper for the box

Cutter for making holes for the switch and led

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?

Tinkercad for simulation

using adaptor 5v as a power source ( both the led & buzzer require no more than 5V. ) and pushbutton
connecting the + of the button with the bread board and the battery
connecting the _ of battery in the bread board

Then the red led, connect it to the beard board and connect - of led with the - of beard board to to limit the current and not burn it I used a 220-ohm resistor

Then the buzzer, connect it to the beard board.

I connected the led and the buzzer in parallel after making sure of their polarity and then connected a resistor with the led to limit the current.

Starting simulation

It needs a 5v adaptor as both the led & buzzer to require no more than 5Vز

simulation

Action outputs: buzzer ( for alerting sound), red light ( for alerting flash)

as object of the game is to carefully move the wire wand loop along the copper wire “maze” without touching it. When the loop touches the wire, you will hear a “BUZZ”. The goal is to be fast and at the same time to be efficient, having the least amount of touches.

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?

1st

First test the circuit on a breadboard, by following what I did in tinker cad and connecting the led to the resistor parallel to the buzzer

2nd

By using a 5v adaptor as it worked both the led & buzzer to require no more than 5V.

3rd

Make the connections between the wire and the circuit

(connect the positive of the buzzer with the movable wire using crocodile and the positive of the circuit with the start point of the stationary wire using crocodile and in the same crocodile using jumper to connect the + to the bread board )

4th

For the box prototyping ;

I used white hard paper and ramped it other the component like a box then made openings using a cutter for the switch and led light

Gathering all the wire and components in one box and opening hole for the red led and the switch

finally

Buzz wire game working

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 had a problem with how the 3 components will work together

so I rewatched the Midweek Self-Practice and start to simulate it on tinker cad

It helped me to understand the concept

I had a problem integrating the terminal of the copper wire in the circuit.

The solution is to connect the positive of the buzzer with the movable wire using a crocodile and the positive of the circuit with the start point of the stationary wire using a crocodile and in the same crocodile using a jumper to connect the + to the breadboard

Final Project

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

VID-20220822-WA0024.mp4

Getting familiar with the electronics and understanding the concept of how the components work together

WOW!

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

The midweek exercise

This is the first time I connected the 7 segments, purple RGB led and understanding the idea and also understanding the breadboard and how it works

Making RC car for the first time

The coolest thing was using the H bridge in the RC car, and how the breadboard works with different components
