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)

the assignment was about to create a circuit that takes two inputs and gives two outputs or more

this is the model I chose to make. I always wanted to save my money from my brother so I chose the coded bank.

Tool Chain

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

I used tinkerCAD for the simulation

used materials :

keypad 3x3

servo motor

Arduino Uno

jumper wires

red led

buzzer

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 keypad which has 4*3 inputs

the device contains two outputs

1- red led light when password is wrong

2- servo motor moves when password is right

led

motor

I used the 9 voltage adaptor as the motor will be more faster and the led will light more powerfully

i didn't use a breadboard to connect them parallel or series, I connected them to the Arduino instantly

tinker cad link

this is the link for the tinker cad simulation

if you want to check just enter the password 147 ( my birthday) then enter # for the motor movement and add any 3 random numbers and enter with # to see the led

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 10

led is connected to pin 11

keypad from 3 to 9

switch in pin 12

code.ino

first I included servo and keypad libraries then I defined the rows and columns in the keypad then i defined some chars and integers like digits 1,2,3,enter,state and counter

then I defined the pins inputs and outputs

then i used a void loop to check the digits entered if they are right then the motor moves 90 degrees if wrong then led switches on

there is a condition at first for the switch if high then do the following if not then stop

motor and led

switch

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 find the library of the keypad anywhere and tried many solutions but nothing worked. as watching YouTube videos on how to install libraries manually but it was a long process so i chose to ask the instructor on what to do

we asked the instructor Eng. Ahmed Ibrahim and he told us its there but under other name.

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.
