Blynk stops working if I use pinMode

This is my first time using blynk and all I want todo is use a virtual button to control a physical led however blynk works fine with the button and in the serial monitor the button displays either 1 or 0 however when I add the led and put the line “pinMode(ledPin, OUTPUT);” it stops connecting to the app. I know its this as when I take out that line of code it works perfectly.

Hardware and software
• Arduino UNO with ESP8266

  Download latest Blynk library here:

  Blynk is a platform with iOS and Android apps to control
  Arduino, Raspberry Pi and the likes over the Internet.
  You can easily build graphic interfaces for all your
  projects by simply dragging and dropping widgets.

  Blynk library is licensed under MIT license
  This example code is in public domain.


  You’ll need:
   - Blynk App (download from AppStore or Google Play)
   - ESP8266 board
   - Decide how to connect to Blynk
     (USB, Ethernet, Wi-Fi, Bluetooth, ...)

  There is a bunch of great example sketches included to show you how to get
  started. Think of them as LEGO bricks  and combine them as you wish.
  For example, take the Ethernet Shield sketch and combine it with the
  Servo example, or choose a USB sketch and add a code from SendData

/* Comment this out to disable prints and save space */
#define BLYNK_PRINT Serial

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

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

#define ledPin 6

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "****";
char pass[] = "****";

void setup()
  // Debug console
  Blynk.begin(auth, ssid, pass);
  pinMode(ledPin, OUTPUT);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "", 8442);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8442);

  if (param.asInt() == 1) {
      digitalWrite(ledPin, HIGH);
    } else {
      digitalWrite(ledPin, LOW);

void loop()
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!

Try putting the pinmode command first.

Just tried that and serial monitor returns this and won’t even connect to network

, len 1384, room 16 
tail 8
chksum 0x2d
csum 0x2d

Try a different sketch… perhaps this is similar enough… adjust specifics like pin numbers etc

I am using as seperate ESP8266 module connected to an Arduino uno, even after using this It still won’t work

Just noticed there but the only way I can get the Arduino to connect to the wifi network again and even run the program is to upload the code again
