Product Details:

UNO is a Simple I/O platform based on open original code and is easy to understand using Processing/Wiring development environment similar to Java and C language. Lets you do interesting things with UNo quickly. Uno can be used with some electronic components such as LED lights, buzzers, buttons, photoresistors and so on. The UNO development environment interface is based on open source principles and allows you to develop more amazing interactive works for free.

Open the original design of the circuit diagram, the development of software interface free download, but also according to the needs of their own modification, simple download procedures, convenient. You can simply use sensors, various electronic connections (e.g., LED lights, buzzers, buttons, photoresistors, etc.) to create a variety of interesting products.

Using the high-speed microprocessing controller (ATMEGA328), the development of the operating interface and environment are very simple and easy to understand, very suitable for beginners to learn.
