ESP8266 Robotics Projects

Hello world

Now, you will write your first program (sketch) for ESP8266 with the Arduino IDE to blink a LED connected to PIN 2 of ESP8266.

You'll need the following things to build the circuit:

• One LED (any color)
• One 1 kilo ohm resistor
• 3V regulated power supply

Connect the components together, as shown in Figure 1.11:
