What my Arduino is programmed to do is take values from my twitter account which are actually Glucose values I’m submitting and telling me whether the value is Low, Normal, or High. There are LEDs attached to the breadboard that light up when the value is withing a certain range. If the values is less than 80; the yellow LED with shine, if it’s between 81 and 159, the RGB LED will light up green, and if it’s higher than 160, red  LEDs will light up.
