LED Lamp
This one is improved by Colour Changing Nightlight / Lamp LED Simple Arduino Project(1) . I think LED Lamp heards very cool, but it only have give a picture of it, and looks not very good, so I have made this lamp, with breath light, and have a shell outside. It can be your night light, and it can also help you to control your breathing.
