			For the ESP8266 use A0 instead of Pin 34.

	This should divide the voltage by half as both resistors are the same - you should read a value of about 2000 (assuming 12Bit resolution with a range of 0-4096)		This should divide the voltage by half as both resistors are the same - you should read a value of about 2000 (assuming 12Bit resolution with a range of 0-4096)
