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?

Digital circuit on TinkerCAD

Components list:

RGB LED - OUTPUT component
4 Pcs resistors; 220 OHM
Servo motor - OUTPUT component
Buzzer - OUTPUT component
BT module HC-05 - OUTPUT component, to control the circuit through smartphone
Arduino UNO board

Digital circuit on TinkerCad

Text Code

Code logic:

Upon clicking #1, screen prints "You entered: "1" and the servomotor changes position from 180° to 0° and the RGB LED radiates the following colors in order Red, Green, Blue and White
Upon clicking #0, screen prints "You entered: "0" and the servomotor changes position from 0° to 180° and RGB LED turns off and the buzzer beeps
Upon clicking #0, screen prints "You entered: "unknown value!" and the servomotor changes position to 0° and the buzzer beeps

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?

Electric circuit on Breadboard

Wired the RGB LED and 4 resistors on the breadboard using jumper wires.
Connected the 4 LEDs to Arduino UNO board same pins sequence on TinkerCAD.
Connected and tested the Servo motor and buzzer.
Afterwards, connected the Bluetooth module HC-05 following the circuit on TinkerCAD.
Lastly, connected the Arduino UNO board to my laptop via the USB cable.
Uploaded the code for troubleshooting and testing.

Mounting circuit onto cardboard

Folded 3D Paper Ball using the white paper.
Reused a cardboard box I had from another project, and turned it into a case for the electric circuit and Arduino board.
Secured the servo motor on the cardboard lid using plastic cable zip.
Used glue to secure the Origami ball in place on the cardboard lid.
Cut a hole underneath the ball for the RGB LED.
Cut 4 holes on the box side to mount the USB cable, 9V adapter, buzzer and BT HC-05 module

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?

As as iPhone user, I wasn't able to install the Bluetooth terminal app to control my project via the Bluetooth module.

My instructors advised to use the smartphone of a friend or family member. I followed the advise and used my mother's smartphone :)
