Esp8266 and Blynk RGB Ligh Control Widget

Need Help With My Project

1

Hi There,
I am having issue with the RGB Light Control and ESP8266, I am trying to control 8x8 matrix of ws2812b leds. I could not make it work on further inspection and debugging raw values from serial monitor, I could see that the string for RGB values is returning normal integer in range 0 to 255 and for half of the colours it is either 0 or 255 and for few colours it varies between 0 and 255. will attach video if possible, Sharing code that i used for debugging as well.
libraries used:
#include <ESP8266WiFi.h> inbulit for wifi
#include <BlynkSimpleEsp8266.h>
Blynk By Volodymyr Shymanskyy
1.3.2 installed

#define BLYNK_TEMPLATE_ID "TMxxxxxxxx"
#define BLYNK_TEMPLATE_NAME "RGBLight"
#define BLYNK_AUTH_TOKEN "xxxxxx"

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

char ssid[] = "xxxxx";
char pass[] = "xxxx";

void setup() {
  Serial.begin(115200);
  Serial.println("Starting Blynk Raw Value Debugger...");
  Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass);
}

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

// ---------------- BLYNK HANDLERS ----------------

// V0 → Integer
BLYNK_WRITE(V0) {
  Serial.print("V0 On/Off (Integer): ");
  Serial.println(param.asInt());
}

// V1 → String
BLYNK_WRITE(V1) {
  Serial.print("V1 Color (String): ");
  Serial.println(param.asStr());
}

// V2 → Integer
BLYNK_WRITE(V2) {
  Serial.print("V2 Brighness (Integer): ");
  Serial.println(param.asInt());
}

// V3 → Integer
BLYNK_WRITE(V3) {
  Serial.print("V3 Animation speed (Integer): ");
  Serial.println(param.asInt());
}

// Sync all values on connect
BLYNK_CONNECTED() {
  Serial.println("Connected to Blynk Cloud, syncing all values...");
  Blynk.syncVirtual(V0, V1, V2, V3);
}

why am i recieving integer value in string, if i am not wrong it should be in format (R,G,B) (120,20,123) this is right string format.
please help in this regard. once this values are coming correct i can proceed with further code. Its actually going to be very simple i dont want anything fancy all 64 leds synced in same color and same brightness only 2 main control

I remembered i can actually see values real time in blynk dashboard itself sharing that clip that shows values in different way. than I see in serial monitor.

Now I am even more clueless how can this be solved

I’ve not used this widget, but from what I understand, the R, G and B values are sent as array elements.
I assume that your code is simply seeing the first array element - which presumably is the Red intensity value.

If you take a look at the documentation and the linked blog post then you should see how to print all three array values.
