Node_MCU_Tutorial-1 : Configuring enviornment in Arduino IDE

       

   
                        NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. NodeMCU was created shortly after the ESP8266 came out. On December 30, 2013, Espressif Systems began production of the ESP8266, NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. Two months later, the project expanded to include an open-hardware platform when developer Huang R committed the gerber file of an ESP8266 board, named devkit v0.9.

IO index	ESP8266 pin	IO index	ESP8266 pin
0 [*]	GPIO16	7	GPIO13
1	GPIO5	8	GPIO15
2	GPIO4	9	GPIO3
3	GPIO0	10	GPIO1
4	GPIO2	11	GPIO9
5	GPIO14	12	GPIO10
6	GPIO12

      We can easily program this node MCU IoT module with the help of Arduino IDE for that we need to integrate the node MCU board package with the Arduino IDE, We  can add node MCU board package to Arduino by the following steps

Step 1:  Open Arduino-IDE,
Select File => Preferences => paste the following link in the Additional Boards Manager URLs: column "http://arduino.esp8266.com/stable/package_esp8266com_index.json"

Step 2:

Then Choose from options Select Tools => Board => Board manager =>ESP8266=> install the package as shown below

With the above two simple steps, you can add Node MCU to your Arduino IDE
