• Hardware model + communication type. For example: ESP32
• Smartphone OS (iOS or Android) + OS version
• Blynk server region
• Blynk Library version
• Post your FORMATTED sketch code. Remove your AUTH TOKEN from code. Don’t post screenshots
• Post your serial monitor output when experiencing some issues
If you don’t format your code, your topic can be deleted by moderators.
Here is a correct example of code formatting:
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = "wgb1tCxb2octL4uwmztOds4WclBLDenV";
char ssid[] = "IOT";
char pass[] = "0939201239";
WidgetLED ledV1(V1);
int vpin_value;
BLYNK_CONNECTED() {
Blynk.syncVirtual(V0);
}
BLYNK_WRITE(V0) {
vpin_value = param.asInt();
Serial.println(vpin_value);
}
void setup(){
Serial.begin(9600);
Blynk.begin(auth, ssid, pass,"blynk.cloud",8080);
pinMode(2, OUTPUT);
pinMode(4, OUTPUT);
}
void loop(){
Blynk.run();
digitalWrite(2,LOW);
if (vpin_value == 1) {
digitalWrite(4,HIGH);
ledV1.setColor("#ff0000");
ledV1.on();
}
digitalWrite(4,LOW);
ledV1.setColor("#ff0000");
ledV1.off();
}
I’m not sure what your question or issue is because you haven’t provided any useful information, but you need to read this and fix your void loop…
