Arduino Original

UNO is a Simple i/o platform based on open source code, and it has the characteristics of easy to understand using Processing/Wiring development environment similar to Java and C language. Let you quickly use uno to make interesting things. Uno can be used with some electronic components such as LED lights, buzzers, keys, photoresistors and so on. The uno development environment interface is based on the open source principle, allowing you to download, use and develop more amazing interactive works for free. Open the circuit diagram of the original design, develop software interface for free download, but also according to the needs of their own modification, download procedures are simple and convenient. It can simply use sensors and various electronic 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 operation interface and environment is very simple and easy to understand, which is very suitable for beginners to learn.

The Micro is a microcontroller board based on the ATmega32U4 (datasheet), developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard. The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
