I recently started playing with the Arduino micro-controller platform and I thought for my first project I should make something easy, but fun and functional.
I posted a ton of photos showing the construction. I purchased all of the materials at Craftwarehouse and the Arduino board from Modern Device. The RGB LED and DC barrel jack I got at Radio Shack and the power source is a recycled 9v wall wart that was for an old RC radio.
An LED powered nightlight is perfect for a child’s room because it has a long life, consumes very little power and most importantly it doesn’t get hot!
I had to turn it off the first night I put it in my son’s room because he wouldn’t go to sleep. Instead he stayed up saying: ‘Oooh, it’s blue.’ ‘Oooh, it’s greeeeeeen.’
