Not sure if it's helpful but... I've got an Arduino starter kit and one of the projects is a 'love o meter' that measures temperature and changes LED outputs based on the values calculated. It also has a terminal for outputting all the temperature readings whose frequency you can control. I've adapted it to create a classroom thermometer that tells me if I need to open a window...
