Control NodeMCU with LED from website using thingspeak from Anywhere in the World

Overview

By this tutorial, we will learn How to Control Esp12E NodeMCU with LED from the website using ThingSpeak from anywhere in the world.

Control ESP12E from thingspeak using web page with LED from anywhere in the world requires a breadboard setup of ESP12E Node MCU with three LED on pin D1,D2,D3 respectively. Before beginning with this tutorial, make sure you have wired it up as shown below. You can also follow this specific lesson where I am explaining the step by step of wiring your breadboard. And return back here after you have setup the breadboard.

Connection Description

1.Connect first LED to Pin “D1” of ESP12E NodeMCU board such that the positive terminal is connected to D1 and negative terminal of LED is connected to GND.
2.Now Connect first LED to Pin “D2” of ESP12E NodeMCU board such that the positive terminal is connected to D2 and negative terminal of LED is connected to GND.
3.Similarly Connect first LED to Pin “D3” of ESP12E NodeMCU board such that the positive terminal is connected to D3 and negative terminal of LED is connected to GND.
