Instruction & Steps of How to use:

1. Download the Arduino IDE, the latest version.

2. Install the IDE

3. Set up your Arduino IDE as:

Go to File->Preferences and copy the URL below to get the ESP board manager extensions: arduino.esp8266.com/stable/package_esp8266com_index.json

4. Go to Tools > Board > Board Manager> Type "esp8266" and download the Community esp8266 and install.

5. Set up your chip as:

  • Tools -> Board -> NodeMCU 1.0 (ESP-12E Module)
  • Tools -> Flash Size -> 4M (3M SPIFFS)
  • Tools -> CPU Frequency -> 80 Mhz
  • Tools -> Upload Speed -> 921600
  • Tools-->Port--> (whatever it is)

6. Download and run the 32 bit flasher exe at Github(Search for nodemcu/nodemcu-flasher/tree/master/ at Github)github.com/nodemcu/nodemcu-flasher/tree/master/Win32/Release Or download and run the 64 bit flasher exe at: github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release

7. In Arduino IDE, look for the old fashioned Blink program. Load, compile and upload.

8. Go to FILE> EXAMPLES> ESP8266> BLINK, it will start blinking.
