Introduction To NodeMCU8266 and Steps to Import ESP Board

Intoduction to Nodemcu8266 & Steps to Import ESP Board Libraries: What is NodeMcu8266

The open source hardware device for IOT is NodeMcu8266. It can be programmed using Arduino IDE, and the coding structure remains similar to that of Arduino. But Arduino IDE does not come with pre-installed ESP supported boards on it, so one needs to add/import the board attachments to the IDE before programming it. It is very simple to do. ESP series boards are not initially developed for Arduino IDE compatibility, therefore in Arduino IDE each pin on NodeMCU corresponds to different GPIO pin for IDE. Here, is the pin mapping of NodeMCU GPIO pins. In Coding you can directly write digital pins of NodeMCU as  D1,D2,D3… or corresponding GPIO pin no. Features:

• Open-source

• Interactive

• Programmable 

• Low cost 

• Simple 

• Smart 

• WI-FI enabled

Specification: 

The Development Kit based on ESP8266, integrates GPIO, PWM, IIC, 1-Wire and ADC all-in-one board. Power your development in the fastest way combining with NodeMCU Firmware.

• Wi-Fi Module – ESP-12E module similar to ESP-12 module but with 6 extra GPIOs.

• USB – micro USB port for power, programming and debugging

• Headers – 2x 2.54mm 15-pin header with access to GPIOs, SPI, UART, ADC, and power pins

• Misc – Reset and Flash buttons

• Power – 5V via micro USB port

• Dimensions – 49 x 24.5 x 13mm

Steps to Import ESP Board Libraries:

• 1. In Arduino IDE, go to File–>Preference

Preference-mechatronicslabrpi<

• 2. In the preference window under the ‘Additional Boards Manager URLs” field, paste this link 

http://arduino.esp8266.com/stable/package_esp8266com_index.json

• 3.Click on the Ok button.

• 4.Go to ‘Tools and Board’, from drop down menu select ‘ Board Manager’.

• 6. When you select the ESP8266 package then a ‘Install button’ will appea, click on it.

This file file is around 160mb in size and will take some time to download.

• 7. After Completion, you will be able to find the different boards of ESP series in Arduino IDE and Installation is complete.
