INTRODUCTION
UNO is a Simple ilo platform based on open source code, and it has thecharacteristics of easy to understand using Processing/Wiring developmentenvironment similar to
Java and C language. Let you quickly use uno to makeinteresting things. Uno can be used with some electronic components such asLED lights, buzzers, keys, photoresistors and so on. The uno developmentenvironment interface is based on the open source principle, allowing you todownload, use and develop more amazing interactive works for free.Open thecircuit diagram of the original design, develop software interface for freedownload, but also according to the needs of their own modification, downloadprocedures are simple and convenient. It can simply use sensors and variouselectronic components to connect (e.g.LED lights, buzzers, keys,photoresistors, etc.) to make a variety of interesting works. Using high-speed microprocessor controller (ATMEGA328), the development of operationinterface and environment is very simple and easy to understand, which isvery suitable for beginners to learn.
