Using the ESP8266 module for the Internet of Things

About two years ago, a cheap five dollar microcontroller has been entering the maker scene, featuring b/g/n wireless LAN.  The ESP8266 is manufactured by a Chinese company, called Espressif Systems and became soon very popular as a building-block for home-automation and IoT projects.These modules were distributed on  Ebay, the Amazon Marketplace or AliExpress for a few dollars. However, communication with most of the ESP8266 modules requires an external USB-to-Serial-Adapter and a special procedure to bring the device into “flash-mode”, which can be cumbersome in some cases, especially for beginners.
