Beginning with Blynk using Arduino uno and ESP8266 wifi shield

Solved

Hey!!

I am very new to blynk app. I am just trying to blink one LED light using a blynk app. Currently I’ve connected my ES8266 wifi shield to my UNO board and for testing when I am typing AT in serial monitor , it returns OK.
I’ve gone through many tutorials, according to them I firstly installed blynk library by going to Settings–> Include Library–> manage libraries, here I searched for BLYNK library and installed with the version 0.4.7

Now I am trying to implement a simple example of Blynk Blink. Here I am getting this:

Sketch uses 18192 bytes (56%) of program storage space. Maximum is 32256 bytes.
Global variables use 677 bytes (33%) of dynamic memory, leaving 1371 bytes for local variables. Maximum is 2048 bytes.

An error occurred while uploading the sketch.

So please help me out in this.

You are running into an issue between your IDE and hardware… not Blynk specific.

Try Googling your error for solutions… for example

try restarting the arduino ide and try changing the usb port of your pc. if this does not help then the atmega 16u2 chip might be a problem. use another uart chip or isp.
