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

cheppy44

@loaffette I am using an ESP 32 dev module, but I would not recommend it if you want to implement this on your board. I have a suspicion your issue has to do with pull up/down resistors. Could you post a picture of what your electronics looks like? The purpose of the resistors is to give the digital inputs a default state. If you leave them unconnected or “floating”, they are subjected to back ground electronic noise and are not reliable. Some micro controller have certain pins that have internal resisters that you can enable.

LOAFFETTE

@cheppy44 I may have forgotten about the resistor...

cheppy44

@loaffette the controller you have may have internal pull up you can enable, that was why I was asking what your electronics situation looks like.

LOAFFETTE

@cheppy44 I'm using an Arduino Uno, a button and two separate LEDs (4 leds per strip.)

Going to add the resistor.

Also, I had a cool idea to add on to it later on that would change the color of the LEDs depending on how fast I'm going, or how fast the motor is spinning

cheppy44

@loaffette that will be interesting! You would probably need an IMU to tell how fast you are moving.

LOAFFETTE

@cheppy44 I actually have one lying around

So i tested it in tinkercad since I don't have any resistors IRL. It works with the pulldown, but only button 2 seems to be detected currently.

Also, I had to change the code up for the LED so that strip 1 is for the left, and strip 2 is for the right since I'm going to be placing them under the fender for now

Updated code:


#define PIN1        3 //Pin for Front Strip
#define PIN2        2  // Pin for Rear Strip
#define BUTTON_PIN1 4   // Pin for Button 1
#define BUTTON_PIN2 5  // Pin for Button 2
#define NUMPIXELS   4   // Number of Neopixels in each strip

Adafruit_NeoPixel strip1(NUMPIXELS, PIN1, NEO_GRB + NEO_KHZ800); //Setup for Strip1
Adafruit_NeoPixel strip2(NUMPIXELS, PIN2, NEO_GRB + NEO_KHZ800); //Setup for Strip1

int buttonState1 = 0;  // variable for reading the pushbutton status
int buttonState2 = 0;  // variable for reading the pushbutton status

uint32_t white = strip1.Color(255, 255, 255); //Defines a color later to be used in strip1.fill (r,g,b)
uint32_t red = strip1.Color(255, 0, 0);
uint32_t yellow = strip1.Color(255, 255, 0);

void setup() {

  pinMode(BUTTON_PIN1, INPUT_PULLUP);  // Pin for button 1 other side connected to ground
  pinMode(BUTTON_PIN2, INPUT_PULLUP); // Pin for button 2 other side connected to ground

  strip1.begin(); // INITIALIZE NeoPixel strip1 object (REQUIRED)
  strip1.setBrightness(4); // a value from 0 to 255
  strip1.show(); // Initialize all pixels to 'off'

  strip2.begin(); // INITIALIZE NeoPixel strip2 object (REQUIRED)
  strip2.setBrightness(4); // a value from 0 to 255
  strip2.show(); // Initialize all pixels to 'off'

  Serial.begin(9600); //start Serial console for debuging
  Serial.println("begin");
}

void loop() {
  buttonState1 = digitalRead(BUTTON_PIN1);
  buttonState2 = digitalRead(BUTTON_PIN2);
  
  // check if the pushbutton is pressed. If it is, the buttonState is HIGH:
  if (buttonState1 == LOW) {
    // turn left turn signal on 
    Serial.println("button one left");
    strip1.fill(white, 0, 4); //strip.fill(color, first led index, number of leds to fill);
    strip1.fill(yellow, 5, 4);
    strip1.show();
    strip2.fill(red, 0, 4);
    strip2.show();
    delay(500); //delay for 500 milliseconds or .5 seconds

    strip1.fill(white, 0, 3);
    strip1.show();
    strip2.fill(red, 0, 3);
    strip2.show();
    delay(500);

  } if (buttonState2 == LOW) {
    // turn right turn signal on
    Serial.println("button two right");
    strip2.fill(yellow, 0, 4);
    //strip1.fill(white, 5, 4);
    strip2.show();
    //strip2.fill(yellow, 0, 4);
    strip1.fill(red, 0, 4);
    strip1.show();
    delay(500);

    strip2.fill(white, 0, 4);
    strip2.show();
    strip1.fill(red, 0, 4);
    strip1.show();
    delay(500);

  } else {
    // turn leds back to "normal" 
    //Serial.println("normal");
    strip1.fill(white, 0, 4);
    strip1.fill(white, 5, 4);
    strip1.show();
    strip2.fill(red, 0, 4);
    strip2.fill(red, 5, 4);
    strip2.show();

  }
delay(50);
}

Update:
Checked the serial output and it does detect the button press, but nothing is changing with the LEDs

update update:
Code works! :) Copied code from the rigth blinker and copied it into the if statement for the left blinker and changed strip1 to strip2 and vice-versa

iam smort

cheppy44

@loaffette sweet! the strip.fill commands are pretty useful when you know how to use them.

LOAFFETTE

@cheppy44 yep!
Tomorrow I'll order the arduinos, some resistors and I'll add them on later on this week.
Need to focus on studying for two exams this week, but also I'd like to do a lot of my Onewheel work when I get everything for the Onewheel in! (This, life savers and the Badgersense!)

cheppy44

@loaffette did you decide which controller you are going to buy? For the application I do thing that any of the name brand arduinos may be a bit big.

LOAFFETTE

@cheppy44 going for the Nano due to its compact size and okay price, though that's what I'm going to be using for now. Later i might switch it up to something else

LOAFFETTE

Update!

The Nano(s) are ordered and will be here next Tuesday! I will begin working on making a mount for the arduino and the battery. I will make a test mount for the battery and I'll probably modify an already existing nano mount for now

LOAFFETTE

Arduino Nanos have arrived!
Won't be able to do any work on them until tomorrow. Got slammed with two exams yesterday and today I've got classes until 5 PM then two homework assignments

Tomorrow, I will work on the arduino and I'll post the results

LOAFFETTE

UPDATE!

Everything is soldered together, but we have a few problems, mostly on my end.
1: Soldering job is horrible and I need to find a better way to connect the wires to the strips and I need actual wire that would be good for soldering. I have wires constantly coming off and I have to solder them back on, so I will have to go and find a way to solder those better..

The LED strip I have are old and a lot of them are broken, and I also don't ahve any resistors.

But the code works with my arduino, I just need some better wiring and better soldering

@loaffette Looking good so far!

cheppy44

@loaffette lookin great!

LOAFFETTE

the battery came off of it's mount after a jump off a curb and the LED wires snapped off 5 minutes into a ride

I am going to do research into how to do wiring better lol

Puzz360

@loaffette excellent job so far… 👍
We can see what FM would have gone through in board development early on eh?
I think now you have a working setup, hot glue and something like epoxy resin? would be good to set everything in place. A little permanent but would help I think… ???

Edit…Heat shrink too

LOAFFETTE

@puzz360 Yeah, that's the plan

I haven't soldered in MONTHS since the school bans anything that generates heat except for the 3D printer I've got in my room. (It's in an enclosure and the school knows about it, and doesn't entire care as long as I don't blow a fuse). My soldering isn't as good as it used to be and I struggled to make good connections on the solder pads and ended up having half of them ripped up. I'll have to order more LEDs and some solid-core wire, though I have an idea. I need to find a 3D scan or model of the fender I have and then design a clip or shell that will go on the edge or buttom of the fender.

I'll be working on 3D printing and designing some test parts for S-Leon's light bar for the badgersense so I'll just throw this project into it as well.

I'll make the CAD files public when they are finalized!

I'll also try and work on an actual enclosure that fits the curve of my current fender as a start.

Since I know the concept can work now, I'll just have to start refining it

LOAFFETTE

Ok, update:
I've had a lot of stuff happening, and I'm trying to deal with it RN. I'm fine, just a little...
tired

This weekend I hope to make the first working and functioning prototype for my RGB headlight project. Found some resistors, buttons and a spare LED strip to use. I also got some actual wire for soldering, and I do plan on 3D printing out cable reliefs for the LED strip connections.

I will post those models publicly when they are tested and ready

LOAFFETTE

Soldered the LED strips up today, and was gonna connect them to the arduino nano, until I realized that there is only one 5v rail on the Nano. Might either run a long wire from the 5V out on one strip and to the other one, or splice two power wires into one..
