Blue Home - Explore the Solar System

Preparing for this lesson will require the instructor to have an Arduino to code, printed cards [design attached], and jigsaw pieces [cut with a laser cutter]. To prepare these things here are the materials needed:

Bill of materials:

• Different colors 15mm Cardboard [6 pieces]
• RGB LED [1 piece]
• Arduino Nano 33 BLE Sense [1 piece]
• Addressable RGB LED Strips each with 3 LEDs [2 pieces]
• Vibrating Mini [1 piece]
• 3D printed Astronaut Piece [1 piece]
• Printed Cards [30 cards]
• Dice [1 piece]
• Diffusive Paper [1 piece]

Preparation:

• Print the game cards. ** design attached in lesson attachments.

• Cut the jigsaw puzzle design using a laser cutter, with different colors of cardboard [10 – 15 pieces of each color] ** design attached in lesson attachments.

• 3D print the astronaut piece, if a 3D printer is not available, then you can DIY and piece that looks similar to the design. ** design attached in lesson attachments.

• Connect the electronic pieces as seen in the picture below [LED stripes, RG LED, Vibrating mini and the Arduino nano].

• Code the Arduino with the available code:

// SENSOR LIBRARY
#include <Arduino_APDS9960.h>

//ADDRESSABLE RGB LED LIBRARY 
#include <Adafruit_NeoPixel.h>

#ifdef __AVR__
 #include <avr/power.h> // Required for 16 MHz Adafruit Trinket
#endif
// Which pin on the Arduino is connected to the NeoPixels?
#define PIN        6 // LED PIN 
// How many NeoPixels are attached to the Arduino?
#define NUMPIXELS 6 // Popular NeoPixel ring size
Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

#define DELAYVAL 500 // Time (in milliseconds) to pause between pixels

void setup() {
  
#if defined(__AVR_ATtiny85__) && (F_CPU == 16000000)
  clock_prescale_set(clock_div_1);
#endif
  // END of Trinket-specific code.

  // The first NeoPixel in a strand is #0, second is 1, all the way up
  // to the count of pixels minus one.
  //for(int i=0; i<NUMPIXELS; i++) { // For each pixel...

    // pixels.Color() takes RGB values, from 0,0,0 up to 255,255,255
 
    pixels.setPixelColor(0, pixels.Color(255, 255, 255));
    pixels.setPixelColor(2,  pixels.Color(255, 255, 255));
    pixels.setPixelColor(3,  pixels.Color(255, 255, 255));
    pixels.setPixelColor(5,  pixels.Color(255, 255, 255));

    pixels.show();   // Send the updated pixel colors to the hardware.

    //delay(DELAYVAL); // Pause before next pass through loop
  //}

  while (! APDS.colorAvailable()) {
    delay(1);
  }
