Arduino is a computer platform based on single-chip microcomputer and open source, and forms by a set of development environment for programming for Arduino plate . It does not need to care about the details of the microcontroller programming trival, but provides a toolkit easy to use. Arduino simplified the work flow of single-chip microcomputer. Compared with other systems, Arduino in many places is more advantageous, especially suitable for junior electronic professional students and some amateur enthusiasts. This paper explored in the college junior electronic information specialty and non-electric professional introducing, and gained good results
