Arduino is an open source hardware for building projects at home, like interacting with your plant, you can simply build a project to sense when the plant needs to be watered, and it will mention you in a tweet telling you to water it!
However, Arduino alone is not that powerful it’s more of a controller on a board, you need some accessories to connect Arduino to the internet, or to make it play music or to connect it to a display screen, these accessories are called shields.
So, to make a cool project you have to buy a lot of shields, but why buy these extra pieces of hardware when you already have them in your smartphone?
That’s the idea behind 1Sheeld, it is a re-programmable shield to Arduino, which allows you to use your smartphone as any shield you want.
It has a platform on your phone that communicates with the hardware connected to Arduino, so you can use your phone to post on Facebook, tweet, as a display screen, as a foursquare shield …etc.
