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)

This week my assignment idea is to design a smart circuit with input and sensor action.

I do this idea because it's a small part of my final project.

Tool Chain

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

I used Tinker cad to design and simulate my electronic circuit,

Then i used Arduino program for coding.

Tools:

Arduino Uno
Ultrasonic Sensor
DC Motor
Jumper Wires
Breadboard

Thinker Cad

Arduino Uno

Ultrasonic Sensor

DC Motor

Jumper Wires

Breadboard

L298N Motor Drive

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?

Tinker Cad Circuit

I started by using Thinker Cad to simulate my circuit and make sure that everything will be OK

I used ultrasonic sensor to run DC motor by adding L293D motor driver

Then i used coding by code blocks on thinker cad with if condition to read ultrasonic sensor with distance < 30 cm, DC motor rotate 180 degree & then wait 1 sec then rotate again

Finally i test the simulation of the circuit as shown in the video

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 used the same components that i used on thinker cad

I used ultrasonic sensor to run DC motor by using L298N motor drive for controlling speed & rounds

I put all wires on breadboard & Arduino

Code

I copied the code text to Arduino program & connected with the circuit

When i was near to ultrasonic sensor with distance < 30 cm, DC motor rotate 180 degree & then wait 1 sec then rotate again

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?

Michael helps us in the lecture to understand pull up pins and why should we add pull up for the push button.

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 asked my instructor Amany about the coding and she helped me because i had something wrong on thinker cad until i fix it.

i forgot to add (read ultrasonic slot) in the code blocks & she told me about it.

Final Project

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

My Cardboard Final Project

My assignment project like my final project but i will replace Ultrasonic sensor with RFID control

WOW!

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

I enjoyed our session exercise, we made Smart Waving Hand with Arduino bu using to different inputs:

Manual Mode with potentiometer
Automatic Mode with ultrasonic sensor
