Help with getting around an Arduino bug

Need Help With My Project
1

Hi
I’ve encountered a really annoying bug in the Arduino IDE that makes my code useless… I’d really appreciate some help with my project and avoiding this bug.
The plan is to make a light for my aquarium with an NodeMCU and addressable RGBW strips. Below are my code and a link the Arduino forum, where I posted about the bug.

#include <BlynkSimpleStream.h>
#include <Adafruit_NeoPixel.h>
#include <TimeLib.h>
#include <WidgetRTC.h>

char auth[] = "MyToken";

#define PIN 2
#define NUMPIXELS 15
#define NUMCOLORS 3

Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);
BlynkTimer timer;

int maxColorPosition;

int fadeTimer;
int fadeTime = 1000;
int fadeSteps = 100;

double intensity = 0;
double currentIntensity = 0;

int setColor[NUMCOLORS];
double setColorProcent[NUMCOLORS];
int color[NUMCOLORS];
double colorProcent[NUMCOLORS];
double currentColorProcent[NUMCOLORS] = {0, 0, 0};
double fadeStepProcent[NUMCOLORS];
double fadeIntensity;

  Blynk.begin(Serial, auth);
  strip.begin();
  Blynk.syncAll();

Welcome to the Blynk forum…

Do you have any questions about how Blynk commands work, or what widget to use for a particular purpose… perhaps some assistance with setting up your Local Server?

Those are the types of questions that we try to help with :wink:

And on that note (aside from the fact that I can compile your code without errors)… Why are you using <BlynkSimpleStream.h> for a NodeMCU, shouldn’t you be using <BlynkSimpleEsp8266.h>

You look like you are setup for an Arduino using an ESP for shield… but a NodeMCU is fully capable of the prefered Standalone mode.

As I said it’s an annoying bug. There’s no logic in why, where and when it’s happening. It just is…

And why I’m using SimpleStream; I haven’t gotten my Node yet, so I’m testing my setup with a regular Uno via USB :wink:

That might have been a good thing to mention up front :stuck_out_tongue:

So, since I can’t find an error in the compiler, and I don’t have a RGBW strip to test… and I really don’t understand this “bug” in the first place… I will have to bail on this particular issue. But I will keep watching in case someone else chips in with some brilliance.
