Arduino is a Development board made by the Some European company (low cost). It is considered, sometimes, a portable computer with the functionality and the ability to build some systems on this. This is a modular platform and the modules can be added to it. There are some other options available that make this development board ideal for robotics or some projects that are less complex, require robust platform and can be extended in functionality easily either with pre-built hardware additions or some hardware (along with software) can be developed. Software can be written and hardware can be programmed by programs bits called sketches. You might want to get some hardware developed for this platform then we are ready to extend that helping hand via the home page payment rules & rules .
