Arduino NodeMcu (ESP8266) Pin Mapping

 Arduino NodeMcu (ESP8266) Pin Mapping 

 If you use  NodeMcu borad  with Arduino IDE the following chart will help to find the pin maping

eg. NodeMCU Pin D1 is equivalent to arduino Pin 5. 

Built in LED of NodeMCU is connected to D4  in arduino programming it equivalent to Pin 2 

NodeMCU      Arduino

 D0      =    16
 D1      =    5
 D2      =    4
 D3      =    0
 D4      =    2
 D5      =    14
 D6      =    12
 D7      =    13
 D8      =    15
 D9      =    3
 D10     =    1
