Hello,
I’m also using this great project, and i’m having some problems with compiling the file.
I’m also kind of a new with arduino.
when Compiling the sketch I get this error message:
‘varSpeed’ was not declared in this scope
I have read this previous forum, where this problem was also discusted, but I couldn’t find a solution to my problem, so could annyone help me?
P.s. I’m using arduino 1.8.9 from the windows store
Already Thanks for your time!
My guess is that you’ve corrupted the .ino file when you downloaded or copied the contents.
Does line 9 of ESP8266-WS28xx-Blynk.ino look exactly like this:
int varSpeed, varRainbowSpeed, varAlertMode, varZone;
Personally, I prefer the Windows installer from the Arduino website.
Pete.
@Thijs_harink I couldn’t get windows to install the Arduino website package. I finally opted for the play store myself. If you find it doesn’t work your not the only one.
the beginning of my sketch looks like this:
So Is there any way to check weather I did something wrong with downloading further?
By the mean time my guess is that there is something wrong with library’s but I don’t know witch one, because when I move line 56-196 upwards in the code the message dissapears, but then other errors occur.
@daveblynk I could try to download the one not from the windows store, but that isn’t reccomended by arduino.
They probably get some form of kickbacks from Microsoft for the promotion of the store. The manual download/install works perfectly.
After creating the wifi_credentials folder and file, the copy/pasted .ino file compiles just fine on my Windows installer based Arduino IDE 1.8.9
We would need to see the actual compiler results to determine if there is any hidden issues.
I reinstalled the arduino software, and also had to update all the esp8266 board managers and librarys, but it gives still the same error.

Oooff… I had to fix your post as you didn’t properly format the posted code/info as dictated in the forum directions.
I suspect that you might wish to start off with much simpler examples to build up your experience before plunging into a much more advanced example like this.
What does your settings.h file look like?
Please post the code, orrectly formatted with backticks, and not a screenshot.
Pete.
oh i’m actually experienced with arduino and building webservers on the esp8266, but not with fastLED and blynk.
my settings.h file is in folder called settings in my arduino library foler.

I don’t see how the compiler will find the settings.h file if it’s not in the same folder as ESP8266-WS28xx-Blynk.ino or you change the include statement to incorporate the path.
Pete.
As @PeteKnight has said, or instead of:
#include "settings.h"
you would need to do
#include <settings.h>
The “” uses headers from local folders whereas <> uses local and global folders (as defined in the Arduino IDE)
Thanks @PeteKnight @JustBertC, That solved one problem!, but there is another one…

So I suggest that there is something wrong with the fastLED library pin declaration, but I couldn’t find it yet by my self. but I already fixed a problem with wifi declaration in the Settings file, where one ‘’/’ too much was’
I don’t really use FastLED, but my guess is that something has changed in the required syntax of the commands between the version of the library that you are using, and the version that was used when the original code was written.
Downgrading g to an earlier version of the library, or googling the error message, is where I’d start.
Either way, it not a Blynk related issue.

Try adding:
#define FASTLED_INTERNAL
before you include the FastLED library…
#define FASTLED_INTERNAL
#include <FastLED.h>
