Getting started with the ESP8266 as an Arduino replacement

In this article, I’ll show you how I did get started with an ESP8266, as a replacement for an Arduino, and they are dirt cheap!

The ESP8266, appears to have been sold as a shield for an Arduino, to provide WiFi functionality to an Arduino. Pretty cool!
But what is even cooler: For most applications you do not even need an Arduino, as the ESP8266 can run as a standalone microcontroller with WiFi on board, and is even more capable than most Arduinos.

This may sound odd, but after my first experiences with the ESP8266;
I’m beginning to wonder how often I’ll be using my Arduino Uno in the future. The little ESP8266 is so cool, faster, more powerful, and has more memory, at a ridiculous price of about $5. And all this in a smaller package with WiFi included!
