Here's a project that might be of interest to anyone wanting to experiment with this new wifi module (ESP8266). It's worked flawlessly for two weeks of testing. With an Arduino Nano and a wifi module (ESP8266) I am sending a text message to my phone whenever my home alarm system is sounding. Complete details of the design and links to source code included in the descriptions of the videos.
