It is now almost 10 hours since my workday has began - what a truly frustrating day! No breaks and almost nothing to show for it. hoping to tuck into a book later and forget all about.  I tried modo again, no luck - emailed Thomas for help. 

Switched my circuit set up and realized my neopixel stick is not working fully. Going to have to replace it.  I was having a hard time again until I realized I was using an older program by accident, so after I re-installed a few things I got my motor controller running, and even got a neopixel to light up at the same time (you can see how bright the neopixels are in the photo). 

I got this working for a tail fin back and forth, but what I want is for there to be a regular speed of swishing, and then bursts of higher-speed swishing at random times. I couldn’t figure this out, so I asked reddit for help, hopefully someone will reply.  Here’s my current code - half is from a neopixel library, the motor part I wrote myself - which is crazy because I hardly know how to use this thing!

Halloween hackaton day 1 / 30.10.2019

Today was the first day of our Halloween Hackathon workshop. Pepjin introduced us the goal of the workshop and then we started exploring different opportunities. For my project, I started exploring led ring. I firstly figured out how to use it on its own, for that I had to download neopixel in order for it to work. As I wanted to progress further, Pepjin gave me a switch so with it I would able to control the intensity of the light. The problem was the code. I had to combine Analog code with Simple (neopixel) code. Pepjin helped me with that. After that my idea was to have a sensor that will sense when a person approaches the light and the light immediately turns on. For that I used led ring and proximity sensor.

This is the following code I used:

// NeoPixel Ring simple sketch (c) 2013 Shae Erisson // Released under the GPLv3 license to match the rest of the // Adafruit NeoPixel 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 // On Trinket or Gemma, suggest changing this to 1

// How many NeoPixels are attached to the Arduino? #define NUMPIXELS 12 // Popular NeoPixel ring size

// When setting up the NeoPixel library, we tell it how many pixels, // and which pin to use to send signals. Note that for older NeoPixel // strips you might need to change the third parameter -- see the // strandtest example for more information on possible values. Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

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

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.

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

void loop() {  pixels.clear(); // Set all pixel colors to 'off'

 // The first NeoPixel in a strand is #0, second is 1, all the way up  // to the count of pixels minus one.

int val = analogRead(A0);            // reads the value of the potentiometer (value between 0 and 1023)  val = map(val, 0, 550, 0, 50);

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

   // pixels.Color() takes RGB values, from 0,0,0 up to 255,255,255    // Here we're using a moderately bright green color:    pixels.setPixelColor(i, pixels.Color(val, val, val));

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

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

2nd Iteration of the LED strip

Progress! Here, the LED strip is behaving as it should, with the correct number of LEDs being accessed from the code, and the animation looping repeatedly through the strip.

Below is the Code used to run the above LED strip. It is using the external library <Adafruit_DotStar.h> , which can be found on Github or installed directly from the library manager in the arduino IDE. Simply install the library and modify the included example sketch titled “strandtest”.

***Make sure to have the correct number of LEDs being accessed for your strip, as well as to set the proper Data and Clock pins that you are connecting to your arduino.

// Simple strand test for Adafruit Dot Star RGB LED strip. // This is a basic diagnostic tool, NOT a graphics demo...helps confirm // correct wiring and tests each pixel's ability to display red, green // and blue and to forward data down the line.  By limiting the number // and color of LEDs, it's reasonably safe to power a couple meters off // the Arduino's 5V pin.  DON'T try that with other code!

#include <Adafruit_DotStar.h> #include <SPI.h>  

#define NUMPIXELS 29 // Number of LEDs in strip

// Here's how to control the LEDs from any two pins: #define DATAPIN    11; #define CLOCKPIN   13;

// (Arduino Uno = pin 11 for data, 13 for clock, other boards are different). Adafruit_DotStar strip(NUMPIXELS, DOTSTAR_BRG);

void setup() {

 strip.begin(); // Initialize pins for output  strip.show();  // Turn all LEDs off ASAP }

// Runs 10 LEDs at a time along strip, cycling through red, green and blue. // This requires about 200 mA for all the 'on' pixels + 1 mA per 'off' pixel.

int      head  = 0, tail = -10; // Index of first 'on' and 'off' pixels uint32_t color = 0xFF0000;      // 'On' color (starts red)

void loop() {

 strip.setPixelColor(head, color); // 'On' pixel at head  strip.setPixelColor(tail, 0);     // 'Off' pixel at tail  strip.show();                     // Refresh strip  delay(20);                        // Pause 20 milliseconds (~50 FPS)

 if(++head >= NUMPIXELS) {         // Increment head index.  Off end of strip?    head = 0;                       //  Yes, reset head index to start    if((color >>= 8) == 0)          //  Next color (R->G->B) ... past blue now?      color = 0xFF0000;             //   Yes, reset to red  }  if(++tail >= NUMPIXELS) tail = 0; // Increment, reset tail index }

PROBLEMS

We are able to turn the light on but we don’t know how to turn the NeoPixel light off when it’s not dark anymore.

Strandtag! Nicht nur zu Hause ist es heiß, hier auch. Bei 80% Luftfeuchtigkeit sind auch 32° manchmal zu viel. Nachts kühlt es nur wenig ab. Heute sind wir Strandtester in Queens. Hier gibt es eine vorgelagerte langgestreckte Insel, den Rockaway Beach. Man erreicht ihn mit der neuen Schnellfähre (oben) von Manhattan aus in 55 Minuten für nur $2.75. Oder mit der Subway Linie A zum selben Preis. Der Ort sieht aus wie ein nettes kleines Dorf am Meer, wenn nicht die Wohnblocks im Plattenbaustil wären. Der Strand ist lang und breit und sauber, was man vom Strand am Vergnügungspark Coney Island leider nicht sagen kann. Der ist in unserer Wertung gestern durchgefallen, daher gibt es auch keine Bilder. 7. August 2018

As I’ve shared in a previous post, I recently signed up for an online workshop hosted by Digital Harbor Foundation.  In this series of workshops, you learn how to build 10 different DIY projects.  The course helps you with step-by-step instructions on how to complete the build.  Along with the printed step-by-step instructions, you also get the live walkthrough of the build.  Each project comes complete with a list of materials you will need for each build, along with support when you bump into troubles along the way.  In this first build, using an Arduino, I learned how to program a Neo-Pixel LED light, which can be used as part of a maker space sign.  Now, for anyone who knows truly knows me, knows that I love big bright lights, especially colorful lights, and this project appealed to my peculiar sensory needs.

While I am unable to outline the directions for the build here, you’ll have to sign up for the workshop for that!  I will share my experience during the process, with a few snaps here and there… First of all, I will have you know that she (me) had no clue as to what she was doing, but that’s okay, both @jonathanprozzi and @shawngrimes were there to field my questions…

Arduino uno

The NeoPixel Light was “LIT!” haha!

Close up of Arduino

Micrograbbers connected to wire jumpers

NeoPixel

During the build, I learned to install a program from the Arduino Library, which caused the lights to “light up”.  You’ll notice below in the strandtest below that you have the ability to customize the pattern and timing of the lights, which is pretty neat.  I am thinking of using the lights to make a Neopixel basketball hoop.  It’s gonna be LIT!!! Like, literally… Haha!  During the build, of course she ran into a little snafu (just learned how to spell that word) during the build when I attempted to connect the Arduino via USB.  I received the error message below and of course, called in @jonathanprozzi for damage control. Of course, he directed me to unplug everything, reboot and reinstall the program to my computer and, yes it worked!  See pics above.

Hurrah!

Til next time,

Peace!
