Controll an led over the internet.(IOT)Internert of things

CONTROL AN LED'S USING NODEMCU AND THINGSPEAK.

There are some steps to make this project:

• Make an account on https://thingspeak.com/.
• create channel on thingspeak.
• Fullfill the code required credentials.
• upload the code to Nodemcu Esp8266 Development Board.

Materials required for this project:

• Nodemcu Esp8266 Development Board.
• 5 mm LEDs (White, Green, Red, Yellow and Blue) Any of these.
• Jumper Wires Male to Male.
• Bread Board.
• Laptop for uploading the code to Nodemcu.
