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)

This week my assignment idea is to communicate wirelessly with a Smart Circuit via a Graphical User Interface that contains at least TWO action components.

Tool Chain

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

I used fritzing to design my electronic circuit,

Then I used Arduino IDE for coding.

And I made the actions with the mobile app (Arduino Bluetooth Control).

Tools:

Arduino Uno
Breadboard
Wires
Resistors 220 ohm
Bluetooth Module
Buzzer
RGB LED (common cathode)

I used fritzing to design the circuit.

I used Arduino IDE to communicate with the Arduino UNO board and give it instructions.

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?

I started by using fritzing to design and make sure that everything was ok.

I connected Bluetooth Module with Arduino on RX & TX and the other pins with ground & 5v on breadboard.

I connected the buzzer with Arduino on pin 7 & the other terminal on GND.

I connected RGB LED with Arduino on pins 2,3&4 with resistor 220 ohm and cathode terminal on GND.

I started with defining all pins on Arduino

RGB LED on 2, 3 & 4
Buzzer on 7

Then I define all pins as output in void setup.

In void loop, I used if condition as:

if the incoming data 1; it will be Red light.

if the incoming data 2; it will be Green light.

if the incoming data 3; it will be Blue light.

if the incoming data 4; it will be White light.

else; the Buzzer works

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 fritzing.

I connected Bluetooth Module with Arduino & breadboard, connected RGB LED with resistors 220 ohm & with Arduino, connected buzzer with Arduino & breadboard.

Finally I uploaded the code.

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)

The red LED in the RGB was not working so I just modified its condition to basically do nothing. I also seeked some help from my friend Belal to check the code with me.
