Hello, 

I'm trying to send voltage data to thingspeak, there are tons of tutorial using the DHT sensor, but I'm trying to send a normal voltage reading from the ESP8266 GIPO 2 to thingspeak. 

I'm trying to do something like this, but only to read voltage output from a sensor. 

can someone do the code for me, I've been trying for months. it should be very simple for you guys, please help me.

Arduino mode or Lua mode?

Here is a way by Lua:

Have a look at the bulk update code for Arduino, it also works for ESP8266.    You can modify the POST command to just do a single channel update using the command structure you can copy from your API Keys page or shown here.
