1/6/2022 TinkerCAD:


I learned how to use TinkerCAD which is a designer application to make 3d models which you can choose to print using a 3d printer.

I made Plankton using directions provided


Building the neopixel circuit

Neopixel circuit

We added a second strip for the battery and adjusted our code for it also light up.

code for two neopixels working

#include <Adafruit_NeoPixel.h>

#ifdef __AVR__

#include <avr/power.h> // Required for 16 MHz Adafruit Trinket

#endif



#define LETTERSPIN 6 // On Trinket or Gemma, suggest changing this to 1

#define BATTERYPIN 10


#define NUMPIXELS 20 // Popular NeoPixel ring size



Adafruit_NeoPixel pixelsLETTERS(NUMPIXELS, LETTERSPIN, NEO_GRB + NEO_KHZ800);

Adafruit_NeoPixel pixelsBATTERY(NUMPIXELS, BATTERYPIN, 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


pixelsLETTERS.begin();

pixelsBATTERY.begin();

}

void loop() {

pixelsLETTERS.clear();

pixelsBATTERY.clear();

for(int i=0; i<NUMPIXELS; i++) {

pixelsLETTERS.setPixelColor(i, pixelsLETTERS.Color(0, 0, 255));

pixelsBATTERY.setPixelColor(i,pixelsBATTERY.Color(0, 0, 255));




pixelsLETTERS.show();

pixelsBATTERY.show();


delay(DELAYVAL);

}

}

Soldering

Soldering is a process to connect electronic components. This process works by using a hot solder tool to melt the solder on the wire to keep it on there forever.

Results

This is the result of using the soldering process

Create your own light pattern

After we soldered our wires we used Arduino to program them. To do this we went to tools, manage libraries, and downloaded adafruit neopixel.. Then, we modified the code of adafruit into the pattern we like.

Acrylic LED Sign

  1. First, I made the prototype base for the led sign using Inkscape. I saved the file as an SVG file after that

  2. Then I put the file on the glowforge and used the laser cutter to cut the pieces out for our box which were made out of cardboard

  3. I assembeled the 6 pieces together with hot glue but I didn't hot glue the top part so I would have space for my led lights

  4. I made the Acrylic Design on Inkscape then my teacher used my svg file to put it on acrylic using a laser cutter

  5. After that I put leds in the bottom of my box which lighted up green. The leds were coding using arduino which had the code saved on it from a while back

  6. Lastly, I hot glued the top piece on and made sure the acrylic design was on top of the leds so it shined as bright as possible. The picture to the left is the final product
