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)

I want to turn on/off the lambs from my phone, adjust the brightness and change the colors of the light depending on my current mood. Also, I want to open music.

So, I will build a simple smart circuit that contains 2 RGB LEDS and buzzer that I will control them wirelessly.

I will Use the Android GUI to control the action components.

Tool Chain

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

Software

Fritzing

to draw the circuit diagram

TinkerCad

to simulate the circuit of the game before making the real circuit

Arduino IDE

For writing the code and run it

Bluetooth Control android application

for controlling in the circuit

Components

Breadboard

for connecting all the components

Arduino Uno

for connecting all the inputs and run the device

Bluetooth Module

for communication with mobile application

2 RGB LEDS

for the light

Buzzer

to produce a sound

Jumper Wires

to connect the components with Arduino and Breadboard

Arduino cable USB

To connect the Arduino with laptop

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?

Circuit View

Firstly, I used Fritzing to design my circuit
Then, I used Arduino IDE to write the code.

At first, I defined the inputs pins as integer values, every pin with its number.
3 pins for RGB led and 3 pins for another one.
pin for buzzer
And character variable with initial data =0

Then defined the color lights and buzzer as outputs

The first Case: When the user click on the button no.1 , the first led will lights red, and the other blue.

The second Case: When the user click on the button no.2 , the first led will lights green, and the other blue.

The third Case: When the user click on the button no.3 , Both of LEDs will light the result color from mix between red, blue, and green.

The fourth Case: When the user click on the button no.4 , the first led will light blue, and the other green.

The fifth Case: When the user click on the button no.5 , Both of LEDs will turn off.

The sixth Case: When the user click on the button no.6 , the buzzer will produce a sound.

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?

At first, I connected the components in the real circuit, and connected the Arduino with laptop using Arduino cable USB and uploaded the code but without the Bluetooth module.

After uploading, I connected the Bluetooth module with the circuit and run the code.

Then, I downloaded the Arduino Bluetooth Control application from Google Store and opened the Bluetooth on my phone and paired it with the module, and finally now I can control in the circuit using the application by pressing on the buttons from 1 to 6 and every buttons have different actions, as shown in the video.

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)

When I upload my code, this error is shown to me. So I asked Menna and she told me that I shouldn't connect the Bluetooth module while uploading the code.

Final Project

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

I learned how to control RGB LED using serial communication via Bluetooth, and I will use the same case 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?

I made a micro robot arm with my team mates Ahmed Osama and Khodary using 3 servo motors.

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.

We learned how to make a pattern game using buttons connected with Arduino via wires. we should write the code in Arduino IDE then connect my Arduino board to the computer and upload the Arduino code, Then we should open another software "Processing-4", and write another code for the game and connect it with the same port, and finally run it.

Eng. Menna learned us how to design using Inkscape and I designed those medals then fabricated them using the laser cutting.
