@wmontg5988,

Here is my sketch. Voltage input up to 10V on Anolog In 0.

Cheers,

Cayenne ESP8266 Shield WiFi Example
Adapted from Blynk's ESP8266_Shield_HardSer Example

This sketch connects to the Cayenne server using an ESP8266 WiFi module as a shield connected
via a hardware serial to an Arduino.

You should install the ESP8266HardwareSerial.zip library via the Arduino IDE (Sketch->Include Library->Add .ZIP Library)
from the Cayenne extras/libraries folder (e.g. My Documents\Arduino\libraries\Cayenne\extras\libraries) to compile this example.

NOTE: Ensure a stable serial connection to ESP8266!
      Firmware version 1.0.0 (AT v0.22) or later is needed.
      You can change ESP baud rate. Connect to AT console and call:
          AT+UART_DEF=115200,8,1,0,0

For Cayenne Dashboard widgets using digital or analog pins this sketch will automatically
send data on those pins to the Cayenne server. If the widgets use Virtual Channels, data
should be sent to those channels using virtualWrites. Examples for sending and receiving
Virtual Channel data are under the Basics folder.
