Week #8 - 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)

Build a simple smart circuit that contains at least TWO action components that you can control wirelessly

fake user detector :

idea is the user knows the real number to move the servo otherwise the buzzer will ring and the motor will move to other direction ( lock ) . I just loved the idea of being the only one to access something and tried to apply it .

Tool Chain

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

I used tinkerCAD for the simulation

used materials :

servo motor

Arduino Uno

jumper wires

buzzer

Bluetooth module

preparation

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?

the device contains Bluetooth module which gives order to servo motor and buzzer through the user

I used BT terminal on android to connect to the Bluetooth module

the device contains two outputs

1- buzzer when the number is wrong (anything except 1)

2- servo motor moves when number is right (1)

tinker cad link

this is the link for the tinker cad simulation

NOTE: I used ultrasonic sensor instead of Bluetooth module as its not available in tinkercad

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?

servo motor connected to pin 12

buzzer is connected to pin 11

Bluetooth module connected to pin 0 1

first we used if condition if input is 0 so motor angle set to 180 and buzzer high if data = 1 so buzzer low and motor angle to 0

code link

for the code I first adjusted the pins for motor and buzzer then I made void loop for Bluetooth module if 1 motor goes by 180 degree and buzzer low if not 1 (0) buzzer high and motor 0 degree knowing that motor start is 90 degrees

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 couldn't fit the motor angle as i wanted i didn't know its origin or its boundaries

I saw a YouTube video says that you can adjust the motor arm by moving it by removing the bolt so I did it and it was a really nice solution.

Final Project

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

getting to know how to design a circuit

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.
