Engineering Kit

Here is my Engineering Kit with all of the parts labeled. I will use these parts to do my project.

Electronics Entry Event

This was the entry event to our electronics window sign project. I created a basic circuit with an LED, a battery, and copper tape to make the light shine through the acrylic lasercut piece

Video of Arduino Blink Assignment

Change the speed of blinking on the LED.

Circuit Picture of Arduino Six

This picture shows the circuit we made with the LEDs. We used this example to make the light on the LED. After that, we tried using different inputs for the Arduino.

Circuit Arduino 6

This is the circuit we created in class. Since all of the LEDs were going to be used on one side, we connected a wire. The wire will be used to connect the inputs D10, 11, and 12.

Picture of Arduino 6

In this circuit, the LEDs light up respectfully. It starts in order from D2, D3, and D4, then D10, D11, and D12. The LED lights up for one second before going to another LED. None of the LEDs ever light up at the same time.

Video of Arduino 6

In this video, you will see the LEDs in the circuit light up in order. The LED colors are green and orange, and there are no specific pattern to when they light up. When the cycle is over, it then repeats all over again.

Neopixel Strip

This is the Neopixel strip that I used with the code. These are the colors I want to be with my hashtag. It's not much different from the colors on the original code, but I wanted to change a few of the colors.

Neopixal Code

// A basic everyday NeoPixel strip test program.

// NEOPIXEL BEST PRACTICES for most reliable operation:

// - Add 1000 uF CAPACITOR between NeoPixel strip's + and - connections.

// - MINIMIZE WIRING LENGTH between microcontroller board and first pixel.

// - NeoPixel strip's DATA-IN should pass through a 300-500 OHM RESISTOR.

// - AVOID connecting NeoPixels on a LIVE CIRCUIT. If you must, ALWAYS

// connect GROUND (-) first, then +, then data.

// - When using a 3.3V microcontroller with a 5V-powered NeoPixel strip,

// a LOGIC-LEVEL CONVERTER on the data line is STRONGLY RECOMMENDED.

// (Skipping these may work OK on your workbench but can fail in the field)

#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?

// On a Trinket or Gemma we suggest changing this to 1:

#define LED_PIN 6

// How many NeoPixels are attached to the Arduino?

#define LED_COUNT 16

// Declare our NeoPixel strip object:

Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

// Argument 1 = Number of pixels in NeoPixel strip

// Argument 2 = Arduino pin number (most are valid)

// Argument 3 = Pixel type flags, add together as needed:

// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)

// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)

// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)

// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)

// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)

// setup() function -- runs once at startup --------------------------------

void setup() {

// These lines are specifically to support the Adafruit Trinket 5V 16 MHz.

// Any other board, you can remove this part (but no harm leaving it):

#if defined(__AVR_ATtiny85__) && (F_CPU == 16000000)

clock_prescale_set(clock_div_1);

#endif

// END of Trinket-specific code.

strip.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)

strip.show(); // Turn OFF all pixels ASAP

strip.setBrightness(255); // Set BRIGHTNESS to about 1/5 (max = 255)

}

// loop() function -- runs repeatedly as long as board is on ---------------

void loop() {

// Fill along the length of the strip in various colors...

colorWipe(strip.Color(245, 66, 117), 200); // Red Pink

colorWipe(strip.Color(220, 53, 232), 200); // Pink Purple

colorWipe(strip.Color(85, 66, 235), 200); // Blue

colorWipe(strip.Color(56, 205, 255), 200); // Baby Blue

colorWipe(strip.Color(0, 120, 255), 200); // Blue Green

colorWipe(strip.Color(85, 159, 250), 200); // Sea Blue

colorWipe(strip.Color(43, 255, 146), 200); // Bright Green

colorWipe(strip.Color(245, 242, 95), 200); // Yellow

colorWipe(strip.Color(247, 210, 87), 200); // Light Orange

colorWipe(strip.Color(247, 151, 87), 200); // Red Orange

colorWipe(strip.Color(255, 255, 255), 500); // Orange

// Do a theater marquee effect in various colors...

// theaterChase(strip.Color(127, 127, 127), 50); // White, half brightness

// theaterChase(strip.Color(127, 0, 0), 50); // Red, half brightness

// theaterChase(strip.Color( 0, 0, 127), 50); // Blue, half brightness

rainbow(20); // Flowing rainbow cycle along the whole strip

//theaterChaseRainbow(50); // Rainbow-enhanced theaterChase variant

}

// Some functions of our own for creating animated effects -----------------

// Fill strip pixels one after another with a color. Strip is NOT cleared

// first; anything there will be covered pixel by pixel. Pass in color

// (as a single 'packed' 32-bit value, which you can get by calling

// strip.Color(red, green, blue) as shown in the loop() function above),

// and a delay time (in milliseconds) between pixels.

void colorWipe(uint32_t color, int wait) {

for(int i=0; i<strip.numPixels(); i++) { // For each pixel in strip...

strip.setPixelColor(i, color); // Set pixel's color (in RAM)

strip.show(); // Update strip to match

delay(wait); // Pause for a moment

}

// Theater-marquee-style chasing lights. Pass in a color (32-bit value,

// a la strip.Color(r,g,b) as mentioned above), and a delay time (in ms)

// between frames.

void theaterChase(uint32_t color, int wait) {

for(int a=0; a<10; a++) { // Repeat 10 times...

for(int b=0; b<3; b++) { // 'b' counts from 0 to 2...

strip.clear(); // Set all pixels in RAM to 0 (off)

// 'c' counts up from 'b' to end of strip in steps of 3...

for(int c=b; c<strip.numPixels(); c += 3) {

strip.setPixelColor(c, color); // Set pixel 'c' to value 'color'

}

strip.show(); // Update strip with new contents

delay(wait); // Pause for a moment

}

// Rainbow cycle along whole strip. Pass delay time (in ms) between frames.

void rainbow(int wait) {

// Hue of first pixel runs 5 complete loops through the color wheel.

// Color wheel has a range of 65536 but it's OK if we roll over, so

// just count from 0 to 5*65536. Adding 256 to firstPixelHue each time

// means we'll make 5*65536/256 = 1280 passes through this outer loop:

for(long firstPixelHue = 0; firstPixelHue < 5*65536; firstPixelHue += 256) {

for(int i=0; i<strip.numPixels(); i++) { // For each pixel in strip...

// Offset pixel hue by an amount to make one full revolution of the

// color wheel (range of 65536) along the length of the strip

// (strip.numPixels() steps):

int pixelHue = firstPixelHue + (i * 65536L / strip.numPixels());

// strip.ColorHSV() can take 1 or 3 arguments: a hue (0 to 65535) or

// optionally add saturation and value (brightness) (each 0 to 255).

// Here we're using just the single-argument hue variant. The result

// is passed through strip.gamma32() to provide 'truer' colors

// before assigning to each pixel:

strip.setPixelColor(i, strip.gamma32(strip.ColorHSV(pixelHue)));

}

strip.show(); // Update strip with new contents

delay(wait); // Pause for a moment

}

// Rainbow-enhanced theater marquee. Pass delay time (in ms) between frames.

void theaterChaseRainbow(int wait) {

int firstPixelHue = 0; // First pixel starts at red (hue 0)

for(int a=0; a<30; a++) { // Repeat 30 times...

for(int b=0; b<3; b++) { // 'b' counts from 0 to 2...

strip.clear(); // Set all pixels in RAM to 0 (off)

// 'c' counts up from 'b' to end of strip in increments of 3...

for(int c=b; c<strip.numPixels(); c += 3) {

// hue of pixel 'c' is offset by an amount to make one full

// revolution of the color wheel (range 65536) along the length

// of the strip (strip.numPixels() steps):

int hue = firstPixelHue + c * 65536L / strip.numPixels();

uint32_t color = strip.gamma32(strip.ColorHSV(hue)); // hue -> RGB

strip.setPixelColor(c, color); // Set pixel 'c' to value 'color'

}

strip.show(); // Update strip with new contents

delay(wait); // Pause for a moment

firstPixelHue += 65536 / 90; // One cycle of color wheel over 90 frames

}

Window Light

This is my Window Light made with the Hashtag File. I'm happy this is how it turned out because the lights are so colorful. One thing that bothers me is that I don't have the speakerphone in the blank space to represent being outspoken.

This is the Video of my Window Light with the lights on and off. We connected the Neopixel strip to the arduino so we could run the colors.

Canva Hashtag

This is the sample of the Hashtag file we created on Google Classroom. This is the Window Light that we laser cut for Neo pixal code.

Empowerment and Change Poster

This poster contributes to the project because our acrylic that lights up relates to the person we researched. We created a hashtag file and a poster about a person who has made a lot of change. The students were supposed to make a hashtag that represents the person and their empowerment/movement. This also relates to the hashtag for the window light.

The major impact that Miriam Makeba made was encourage the citizens and others to speak up about South Africa's apartheid regime in the 1960s to 1980s. She also associated with radical activity not just against the apartheid, but with the civil rights movement as well.
My hashtag aligned with Miriam Makeba because although she was denied reentry into her own country, she continued to speak out on the problems the citizens were facing in her country. So, my hashtag, #alwaysbeoutspoken, aligns pretty well with Miriam.

Design Process

Brief - Guidelines that lead to a final results or questions that you feel need an answer or solution. Can be something that is interesting to you or some problem that is given

Research - Looking up information that is relevant to your brief or answers your questions. This can include published papers, images that could be used for design inspiration, and other solutions to the problem that you may have found. Also asking other questions to get to a final wanted result are welcome during this step

Idea and Brainstorming - Using your research, come up with ideas that lead to a solution to your original brief/driving question . This can include designs for the items, solutions to research questions, and other additional items that may be needed for answering your questions.

Prototype - Taking your ideas from the previous step, come up with a physical object that you can you use in the next step of the process. If you are working on a questions or research based project, this is when you will come up with a finalized version of your big question or hypothesis that will be used in the next step of the process

Testing - Taking what you have done in the Prototype step, begin to run some form of testing in order to collect data that can be used to help prove what was done either a 100% success or a 70% still needs some modifications. This step usually have a form of procedure that goes with it, whether it be a series of physical test done by yourself or a large data collection to prove a theory

Evaluation - Looking back over the data from the test, this step allows you to look over the data from your test and figure out if you need to rework something. This step is unique because it can happen at any point in the process, once you are very comfortable in using it, and it can also take you back to any step. For instance, you are building a prototype but it fell apart before you even had a chance to test, which means you have to go back to ideas and brainstorming a way to fix it. You inadvertently pushed yourself through the rest of the design process and back to coming up with an idea

Reflection

Something I found most challenging this semester is keeping up with the files from my arduino and working on a different type of computer. I could overcome this with the help of Mr. Wilson. Other than that, I had no real problems with the Engineering work we did this semester.

I can say that I'm proud of the fact that the actual coding that we did on the arduino worked. I was impressed that I could follow along with the directions and have my work operate properly.
