Extra LEDs For the Onewheel (Because RGB adds a 15% preformance boost)

LOAFFETTE

@lia I forgot which kind, though they have a 5V power line, a data, then ground line.

Lia

@loaffette Try them with the standard neopixel library, if they work they're likely something like WS2812B leds as they're super common.

They're addressable so you can send sequences of data to turn specific ones on/off and change the colour :)

LOAFFETTE

@lia I'll give it a try then!

Also currently 3D printing and testing out the rail clips first to see if they would work out

@loaffette Alright hear me out. Get a Seeed Studio XIAO nRF52840 Sense. It has a built in IMU and could attach it to glove or wrist guard and have it detect when you stick your hand out one way or the other. Then you use the bluetooth radio to send a message to another controller that tells the lights to blink for turn signals. The XIAO also has a built in battery charge circuit for easy integration! https://amzn.to/3Rh30rc

LOAFFETTE

@cheppy44 It's possible and would be cool but that's a huge leap

I'm still at the phase of trying to figure out where to mount all of this stuff and seeing if I can get the code down. Maybe when I have mounting down and I have code that works then I'll look into it.

You don't build the rocket if you don't know if it will take off

Thanks for the recommendation though!

LOAFFETTE

The beauty of the engineering process!

So, I got the clips to stay on, found the right clip model that works, and it sticks pretty well!

So, I printed this puppy out!

LEDs would mainly face the ground but also back and fourth for the initial design. Need to add some more width so the LED strip and fit inside but it works for a proof of concept.

I stuck a pair on my board without the strips, and just rode through the day.

They looked fine

Welp.
So, it got completely olbiterated. The clip also shifted around a lot, and the LED strip would have been shredded into little strips (hah) if I had them on there.

The next idea could be under the fender actually.
Kind of like a lighting kit for a car or something.
The only problem would be leaves, dirt and water but I could probably put them in an enclosure or something.

I've been thinking about the footpad idea and I might work on that later, maybe during the summer when I have some more time and I have a summer job.

Got the code down, but there's an issue with making the LEDs blink continuously.
No luck with making the code work with buttons and stuff, so I'll have to either ask a programmer friend to cook something up or just keep at it

cheppy44

@loaffette what controller are you using with the LEDs? I am more than willing to try and help out with your code!

LOAFFETTE

@cheppy44 probably an arduino Nano or something small.
I have an uno that I could use for testing if I can get a printer cable (Not serial/parell) but I wouldn't take it out on a ride and I'm unsure if it works.

The code:

#include <Adafruit_NeoPixel.h>

int buttonPin = 4;    // momentary push button on pin 0
int oldButtonVal = 0;
#define pixels 8  
#define PIN 3    // Parameter 1 = number of pixels in strip

Adafruit_NeoPixel strip = Adafruit_NeoPixel(pixels, PIN, NEO_GRB + NEO_KHZ800);

int nPatterns = 2;
int lightPattern = 1;
uint16_t currentPixel = 0;// what pixel are we operating on
uint16_t led=0;

unsigned long previousmillis = 0;
unsigned long time = 50;
// the setup routine runs once when you press reset:
void setup() {
  strip.begin();
  strip.show();                // initialize all pixels to 'off'    
  currentPixel=0;                           // initialize the BUTTON pin as an input
  pinMode(buttonPin, INPUT);
  digitalWrite(buttonPin, HIGH);  // button pin is HIGH, so it drops to 0 if pressed
}


void pattern1() {

 strip.setPixelColor(0, 255,255,0);
 strip.setPixelColor(1, 255,255,0);
  strip.setPixelColor(2, 255,255,0);
  strip.setPixelColor(3, 255,255,0);
 strip.show();
 delay(10);
  strip.setPixelColor(0, 0,0,0);
 strip.setPixelColor(1, 0,0,0);
  strip.setPixelColor(2, 0,0,0);
  strip.setPixelColor(3, 0,0,0);
 strip.show();
 delay(10);
  }
 


// Pattern 2 - Red light, all LEDs in the strip are red
void pattern2() {
  strip.setPixelColor(led,0,0,255);
  strip.show();
  led++;
  if(led == pixels){
    led = 0;

  }
  currentPixel=0;
}



// the loop routine runs over and over again forever;
void loop() {
  // read that state of the pushbutton value;
  int buttonVal = digitalRead(buttonPin);
  if (buttonVal == LOW && oldButtonVal == HIGH) {// button has just been pressed
    lightPattern = lightPattern + 1;
  }
  if (lightPattern > nPatterns) lightPattern = 1;
  oldButtonVal = buttonVal;

  switch(lightPattern) {
  case 1:
    if ((unsigned long)(millis() - previousmillis) >= time) {
      previousmillis = millis();
      pattern1();
      break;
    case 2:
      if ((unsigned long)(millis() - previousmillis) >= time) {
        previousmillis = millis();
        pattern2();
        break;

      }
    }
  }
}

I figured the issue you are having with the lights strobing. In your pattern1 you have delay(10) which will only delay it for 10 milliseconds. I changed the 10 to 1000 for one second and here are the results.

I also recommend changing your "time" variable name to something else such as "timer". There are certain variable names that are reserved for other things.

Check out the Neopixel Uber Guide for a bunch of information about the leds and the library. For example you can set the whole "strip" to a color with a single line of code, instead of having to create a function to iterate through the addresses.

@cheppy44 You are a life saver, holy crap

all I need to do is add a part so if I use a second button, I can control the other four LEDs

Puzz360

@cheppy44 good find…. 👍
Typical… NOT available on Amazon UK or EBay UK !!!
Edit…. Found it in RS;)
I think maybe sticking one on the helmet and using voice commands could be an idea, easy to keep PSU and device safe top end (hopefully).

cheppy44

@puzz360 let me know how it goes! I am tempted to pick a few up to experiment with.

LOAFFETTE

@cheppy44 struggling with the code currently. Trying to have two button inputs and two switch functions but nothing is working for the other LEDs

cheppy44

@loaffette what are you trying to have the buttons change?

LOAFFETTE

@cheppy44 if I understand your question correctly, I want one LED to control half of the LEDs (for the left side), and another button control the other half (right side)

cheppy44

@loaffette ahh ok so you want 1 button each for a left turn and a right turn.

LOAFFETTE

@cheppy44 yep!

And I don't know how to get that to work

cheppy44

@loaffette I am setting up the electronics to try and write the code for it. I might start from scratch with the code, but I can try to explain the code I end up writing! I dont exactly want to rob you of learning how to do this, but it sounds like a fun small project to work on for me.

LOAFFETTE

@cheppy44 Thanks man!
I really owe you for this one! I'm pretty bad at programming and this really helps!
I'll probably get around to building a controller for this and designing a mount for the arduino and the LEDs. Found that under the fender is the only safe bet for now, and the footpad would be a pain.

May look at doing on the fender itself (On top) could be an option.

cheppy44

@loaffette here is a demo! still working out a few kinks
