WHAT WE ARE DOING

WHY WE ARE DOING IT

Translating hand-drawn patterns into digital drawings for precise-cuts

You will learn Rhino a powerful tool for both 2D and 3D design

؜ACTIVITY PROMPT

ACTIVITY MATERIALS

• Surface-Based Modeling Software
• Uses NURBS curves
• Used to Design, Edit, Transform, Represent & Manufacture  2D and 3D objects

WHAT WE ARE MAKING

WHY WE ARE MAKING IT

You will create a 3D structure from a cut-out cardboard shape, exploring how light and shadow interact with the form you build.

To learn about the principles of light and shadow, from 2D shapes to 3D objects

ACTIVITY MATERIALS

1st

Sketch Your Shape (5minutes):

2nd

Cut Out the Shape (5 minutes), making sure to keep both the cut-out piece and the negative space (the hole left behind).

3rd

First Light Projection (10 minutes): Place your cut out in front of a flashlight or lamp in a darkened room.

4th

Build Around the Cut-Out (20 minutes): Use the cut-out piece and other cardboard scraps to build a 3D structure around the negative space.

5th

Second Light Projection (10 minutes): Place your 3D structure in front of a flashlight or lamp in a darkened room. Observe the shadow it casts on the wall or a piece of paper. Compare the new shadow to the original one.

1st

Sketch Your Shape (5minutes):

Begin by sketching a simple shape (e.g., a star, heart, or geometric pattern) onto your piece of cardboard.

2nd

Cut Out the Shape (5 minutes):

Carefully cut out the shape from the cardboard, making sure to keep both the cut-out piece and the negative space (the hole left behind).

3rd

First Light Projection (10 minutes):

Place your cut out in front of a flashlight or lamp in a darkened room. Observe the shadow it casts on the wall or roll of paper.

4th

Build Around the Cut-Out (20 minutes):

Use the cut-out piece and other cardboard scraps to build a 3D structure around the negative space. Be creative in how you attach and layer the pieces to create depth and form.

5th

Second Light Projection (10 minutes):

Place your 3D structure in front of a flashlight or lamp in a darkened room. Observe the shadow it casts on the wall or a piece of paper. Compare the new shadow to the original one. Notice how the addition of the cut-out piece alters the shadow’s design.

WHY WE ARE DOING IT

؜Learn about Arduino

Integrating interactivity into your projects

Arduino Board

Breadboards

Allows you to connect different components together when you need to share things like POWER (5V and GND).

Arduino is a small computer that uses code to tell it what to do, like turning lights on and off (We use a software to program it).

Vocabulary

Concepts to Understand

1. Circuit: A closed path for electricity to flow.
2. Voltage: Electrical pressure that pushes current.
3. Current: Flow of electricity.
4. Resistance: Opposition to current, measured in ohms.
5. Serial Monitor: A tool in the Arduino software that shows messages sent from the board.

Hardware Basics؜

1. Digital Pin -- Sends or reads ON/OFF signals (HIGH or LOW).
2. Analog Pin -- Reads varying voltage levels (0–1023) from sensors.
3. GND (Ground) -- Reference point in the circuit. All components must connect to it.
4. 5V / 3.3V -- Power output pins for components.
5. Resistor -- Limits current in a circuit to protect components.
6. Sensor -- A component that detects physical input (light, temperature, sound, etc.).
7. Actuator -- A device that performs an action (like motors, LEDs, buzzers).

Vocabulary

؜Programming Terms

Sketch -- An Arduino program written in C/C++.

Setup() -- Function that runs once at the start. Used to initialize things.

Loop() -- Function that repeats forever while the Arduino is on.

DigitalWrite() -- Sends HIGH or LOW signal to a digital pin (like 0/1 or ON/OFF)

DigitalRead()-- Reads HIGH or LOW signal from a digital pin.

AnalogRead() -- Reads a value (0–1023) from an analog pin.

AnalogWrite() -- Sends PWM signal (0–255) to a pin.

Delay() -- Pauses the program for a number of milliseconds (like to blink a light)

Variable -- Stores data like numbers or text.

Function -- A block of code that does something specific.

Library -- Extra code packages you can add to use sensors or displays easily.

1st Instal the Software

؜Refer to the "resources tab" in this activity folder and learn how to install the Arduino software

Once you have your program installed, you can now program you arduino board !

This is the typical breakdown of a code

2nd Arduino Programming

Synthax

؜ ; ... goes at the end of most lines

{ } ...opens/closes blocks like if, setup, and loop

Press Tab to indent code inside { }

This example shows the simplest thing you can do with an Arduino to see physical output: it blinks the on-board LED.

Hardware Required

1. Arduino Board
2. LED
3. 220 ohm resistor
4. Laptop
5. Arduino Software

BLINK LED

3rd Build the Circuit

Tell the software that you have plugged your arduino

4th Set up your Arduino

؜After you build the circuit plug your Arduino board into your computer, start the Arduino Software (IDE) and enter the code.

5th Insert the Code

؜The first thing you do is to tell the code that our LED is connected to pin 13. This means you need to replace all the LED_BUILTIN to 13

// the setup function runs once when you press reset or power the board

void setup() {

// initialize digital pin LED_BUILTIN as an output.

pinMode(LED_BUILTIN, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)

delay(1000); // wait for a second

digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW

delay(1000); // wait for a second

}

6th Prepare the Code

BLINK LED

Verify and upload your code! and see how you LED starts to Blink!

Change the delay, you can increase or decrease the number!
