This is a Keyestudio Version of the original Arduino UNO board that has all the components of the Arduino UNO, but works exactly the same as the original Arduino UNO but for a much cheaper price! Arduino boards can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
