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

LOAFFETTE

This really helps me out with getting this going!
I'll give the code a spin in Tinkercad when I have time later tonight!

LOAFFETTE

Got the button code translated to work for the Arduino! Just had to change (INPUT_PULLUP) to (INPUT).

Tinkercad simulator is a bit broken though currently, and it's running slow. I'm gonna go and try to find a USB cable for the arduino and test it using real hardware instead.

Again, thank you so much for helping me out with the code!

LOAFFETTE

No dice yet.
The arduino isn't recognizing the button press.

Gonna try and see what I can chagne or what I can do

Changed the } if (buttonState2 == HIGH) {
to LOW instead of high, and found that when I hold it down, it pauses the flashing

LOAFFETTE

@cheppy44 So I messed around a bit with the code to try and make it work

Added a fuction that would print to the console if button two wasn't pressed.
I don't have anything plugged into the pin for button 2 or 1 and it's reading that button one is pressed..

Could my arduino be messed up?

what board are you using, I might try and buy the board you have instead.
Also, when I have the button plugged in and I hold it down, the LEDs stop flashing but are stuck on red

@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
