Week 6 - 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)

The inspiration from this idea is What if use the ultrasonic sensor to help blind people To avoid bumping into things with ultrasonic sensor destines and buzzers to make sound an alarm. we can put this on shoes or any garment they wear it

Tool Chain

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

USED SOFTWARES

I used tinker cad to design and simulate the circuit and the resistor calculator to calculate the ohm of the resistor.

I use this software to upload the coding text and corrected it too and transfer it to Arduino

MATERIALS

Buzzer

Ultrasonic sensor

LED

arduino usb

Breadboard

Arduino

Male jumper

Resistor

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 this project, I used four outputs (light) Red Led/green Led / yellow led, and a buzzer
I use an ultrasonic sensor to measure the distains

I used male wire to connect the led to the breadboard and all components to Arduino
I used a resistor for the led, connect all together as shown in the video below.

the Second step was to make a circuit for led to make sure it is working

The first step was to make a circuit on tinker cad

here it is working

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?

here I started to make the actual circuit i connect the cathode with Resistor and (-) line on the beard board

then I linked the ultrasonic to the breadboard vcc to + line and ground to - line

then attach the anode for each of led to Arduino green led to pin 6

red to pin5- green to pin- 3 )

line trig to pin 8 eco to pin 7

here is the final result on tinker cad

the tinker cad link

here I linked the buzzer + with + line at bread board

and another side to pin 9

Then I write the code to upload it to Arduino

I want to when the object is 50 cm or less away the buzzer makes sound and green led opens another condition when the object is 30 cm or less away the red led opens and when the object is 10 cm or less away the yellow led opens

here is the final result I got from coding when the Distance

is < 50cm the green led opens and the buzzer makes a small alarm the second condition is when the Distance is < 30 cm the red led is open and the buzzer to

the third condition when the Distance < 10 cm the yellow led is open and the buzzer with long tone

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)

here I was so struggling to write the block code i try to make it right

also here I try to write in anther way and didn't work too

and there is also a problem the buzzer is working all time then realize I was the link to the side of the buzzer the wrong way then i was exchanged and it is working

here is the result when the code is wrong all of led open and the buzzer work all the time

then I ask on slack and hams help me a lot to write the block code in the right way Thanks Hamosaa

Final Project

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

here is the final result I got from coding when the Distance

is < 50cm the green led opens and the buzzer makes a small alarm the second condition is when the distance is < 30 cm the red led is open and the buzzer to

the third condition when the distance < 10 cm the yellow led is open and the buzzer with long tone
