Compatibility with Official Arduino IDE, Software, Sendsors and Codes Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board. For the reason of open source, the manufacture of Arduino boards and software distribution by anyone is permitted. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits. Learn Electronics and Programming The UNO boards can be used as the brains behind almost any electronics project. UNO can interact with buttons, LEDs, motors, speakers, GPS units, cameras, the internet, and even your smart-phone or your TV! By connecting the UNO board with a personal computer via a USB cable and uploading programs to the board, users can create digital devices and interactive objects that can sense and control objects in the physical and digital world like robots or even honest fortune-telling machines. This Kit is suitable for 10-year-old and up. Younger kids should be under supervision and guidance of adults.
