Since the Arduino UNO has very limited RAM we need to put the data somewhere. The Catalex MicroSD card reader provides us with the storage we need, is relatively cheap and sold at Kjell o Co (The MicroSD cards on the other hand might be a tad expensive). The second thing we need is an

This is not an easy task, but it explains the basics for setting up a wireless network through Arduino. Basically there are a two sites that when combined gives the right information: http://www.instructables.com/id/Using-the-ESP8266-module/?ALLSTEPS http://shin-ajaran.blogspot.se/2014/12/noobs-guide-to-esp8266-with-arduino.html The 3.3v seems to work fine and the module looks happy. The output isn’t spot perfect so there might be some
