Led strip controlled via arduino uno with Blynk

Need Help With My Project
1

Hey there, this is my first time making one of these so please be gentle.

So I have been trying to get my Arduino Uno to control my RGBW digital led strip that I have bought, how ever the only code I have found to control led strips is for only the ESP8266 chips and not the arduino uno.
I have tried to frankenstein the code( I’ve tried my best to get to learn the code as well and still am learning) what I did is I took the code for the ESP8266 and tried to mix it into the serial USB example sketch from the arduino IDE, low and behold I ran into errors.

Here is the ESP8266 code:

#include <Adafruit_NeoPixel.h>
#include <SPI.h>
#include <BlynkSimpleEsp8266.h>
#include <ESP8266WiFi.h>

#define PIN D2
#define NUMPIXELS 30
#define BLYNK_PRINT Serial
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup()
{
Serial.begin(9600);
Blynk.begin("Authentication Token", "SSID", "Password");
pixels.begin();
}
BLYNK_WRITE(V2)
{

int R = param[0].asInt();
int G = param[1].asInt();
int B = param[2].asInt();
Serial.println(R);
Serial.println(G);
Serial.println(B);
for(int i=0;i<NUMPIXELS;i++){

pixels.setPixelColor(i, pixels.Color(R,G,B));

pixels.show();
}
}

void loop()
{
Blynk.run();
}

Here is the example Blynk serial to usb :

#define BLYNK_PRINT DebugSerial


// You could use a spare Hardware Serial on boards that have it (like Mega)
#include <SoftwareSerial.h>
SoftwareSerial DebugSerial(2, 3); // RX, TX

#include <BlynkSimpleStream.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";


void setup()
{
  // Debug console
  DebugSerial.begin(9600);

  // Blynk will work through Serial
  // Do not read or write this serial manually in your sketch
  Serial.begin(9600);
  Blynk.begin(Serial, auth);
}

void loop()
{
  Blynk.run();
}

So what I’ve ended up with is a really messy piece of code and I would really appreciate it if someone could direct me in what I’ve done wrong as with all the research I’ve done I came up empty on any examples on arduino uno’s code for controlling led strips.

Here is the mess I’ve made:

#include <Adafruit_NeoPixel.h>

#define PIN D7
#define NUMPIXELS 150
#include <SoftwareSerial.h>
SoftwareSerial DebugSerial(2, 3); // RX, TX

#include <BlynkSimpleStream.h>

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

void setup()
{
Serial.begin(9600);
Blynk.begin("Authentication Token");
pixels.begin();
}
BLYNK_WRITE(V7)
{

int R = param[0].asInt();
int G = param[1].asInt();
int B = param[2].asInt();
Serial.println(R);
Serial.println(G);
Serial.println(B);
for(int i=0;i<NUMPIXELS;i++){

pixels.setPixelColor(i, pixels.Color(R,G,B));

pixels.show();
}
}

void loop()
{
Blynk.run();
} ```

What I'm trying to make is that I can use a zeRGBa to control the color and then add a slider for the dimming of the strip.

So sorry if I have laid this our wrong or used the wrong lingo or tags.

Any help is appreciated <3

Kind regards

@Jared please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:

Thanks for that, I was wondering how people displayed their code :smiley:

It’s explained in the text that you deleted when you created this topic, and in the Welcome topic.

Posting a screenshot of your coding attempt doesn’t help at all, as people can’t copy/paste/run it to see where the issues are.

I need to pay more attention then :smile:
