I've been recently looking in to a project that includes an Arduino and LEDs. The idea is that the LEDs will be activated by finding strings of text located in either a text doc, csv doc, or (hopefully) a MySQL database. Any one of those documents would be updated in real-time and it is my hope that Arduino would have the ability to read them in real-time or near real-time. I have no experience with MySQL, but I know it is possible to pipe the data being created in to a MySQL database. I guess the important question would be, is this even possible? Can you point the Arduino to any one of these files (or however MySQL is structured) and have it sift through the text for a string that would enable an LED (what would essentially be a warning). Any ideas would be appreciated.
