Hey! I’m currently using an Arduino UNO with an esp8266 and this esp8266 adapter
and I’m trying to control servo motors via blynk. For now, I´m using code from a youtube tutorial which is proven to work. Although, when I’m booting up the Arduino with the provided code I get the error: esp not responding. When I control the esp8266 via AT commands through serial monitor I can connect to wifi and get IP. Therefore I’m assuming the esp8266 works fine with the following wirering. Do you guys have any ideas as to why this occurs?
// Ekan
vcc adapter --> 5V arudino
rx adapter --> prin 0 arduino
tx adapter --> pin 1 arudino
ground adapter --> ground arduino

WARNING!
It's very tricky to get it working. Please read this article:
http://help.blynk.cc/hardware-and-libraries/arduino/esp8266-with-at-firmware
This example shows how value can be pushed from Arduino to
the Blynk App.
NOTE:
BlynkTimer provides SimpleTimer functionality:

App project setup:
Value Display widget attached to Virtual Pin V5
