Electric circuit on Breadboard
Electric circuit on Breadboard
Wired the 4 LEDs 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 ultrasonic sensor.
Afterwards, connected the on/off switch 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
Mounting circuit onto cardboard
Folded 3D Polygon Paper Ball using the mirror paper.
Covered the cardboard side with the same mirror paper for reflection.
Cut a rectangle hole to mount the servo motor and 4 small holes for the LEDs.
Reused a cardboard box I had from another project, and turned it into a case for the electric circuit and Arduino board.
Cut 4 holes on the box sides to mount the on/off switch, USB cable, 5V adapter and the ultrasonic sensor.
Final output:
Overcoming Challenges
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?

While mounting the components onto cardbaord box, it was challenging to keep the Arduino board in place.
So I purchased an Arduino acrylic case to make it more compact and easier to secure in place using a plastic cable zip.
