Week #7 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)

Security system

The idea for this week assignment is to create a security system for homes that can detect nearby bodies and alert us using Buzzer and LED

Tool Chain

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

Softwares:

TinkerCad.
Arduino IDE: To Program the Arduino Board.

Components Used:

Arduino Uno Board
1 LED.
Jumper Wires.
1 (1 OHM) resistors.
Ultrasonic Sensor.

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?

First I started with Tinkercad to simulation for my circuit and components

Next I connected all parts on Tinkercad.

Then start

For the code I wanted my device to respond as follow:

If any body is come close to the Ultrasonic sensor the device start Buzzing and Blinking.

also I wanted to control the state of the device using an ON/OFF switch

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?

Using Breadboard, I connected all the compartments together in parallel with the power supply and Switch.

Now my Smart device is ready, Lets play around!

Finally I started working on the enclosure design.

And simply it was only a box that represents houses.

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?

Our colleague, Shrouk Gamal was facing a problem in editing her journal using mobile. so I did helped by telling her the right way to do so

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 was trying to add an ON/OFF switch to my circuit. But I was facing a problem on how to connect it despite I'm not using a power supply and only getting power needed from Arduino.

and to overcome this problem, I decided to connect the power switch to the GND PIN comming from the Arduino.

Final Project

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

After learning the logic behind controlling LEDS using ultrasonic sensor, I can implement this knowledge in my 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?

The coolest thing is learning how to use different sensors to control different outputs

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.
