This arduino controlled coaster was created to help me stay on top of my water consumption at work. Each LED is lit blue for exactly 1 hour before turning green, letting me know that I should have consumed one 8oz glass by he time the next led is lit. By the end of the work day I should have finished eight 8oz glasses. If you go over 8 hours, a new color is introduced to help in keeping track. The timer was sped up for the sake of the video.
