  Step 1

  Components

  1. One ESP8266. (I used NodeMCU 1.0, but other versions will also be fine)
  2. One LED
  3. One 220 Ohm Resistor
  4. One Breadboard (I used a Small Breadboard but any other is just fine)
  5. 2 Female-Male jumper wires

  Step 2

  Connect the Resistor and the LED

  1. Place the 220 Ohm Resistor on the Breadboard as shown on Picture 1
     
  2. Connect the Place the LED on the Breadboard so the Cathode end (The shorter one) is connected to one end of the Resistor (Picture 2 and 3)
     
  3. Connect Ground wire (Black wire) to the other end of the resistor (Picture 4)
  4. Connect "LED wire" (Yellow wire) to the Anode (The longer end) of the LED (Picture 4)

  Step 3

  Connect the ESP8266 Module

  1. Connect the other end of the Ground wire(Black wire) to the Ground pin of the ESP8266 module (Picture 1)
     
  2. Connect the other end of the "LED" wire(Yellow wire) to the Digital pin 2 of the ESP8266 module (Picture 2)
     
  3. Picture 3 shows where are the Ground and Digital 2 pins in the NodeMCU 1.0 that were connected on this step
