Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing) . Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. Flash, Processing, MaxMSP) .
This Arduino 328 board provides a USB connection that has been designed to upward for special use. Besides, it is easily to connect when you using a USB cable at around narrow space. In addition, it is a microcontroller board, which can be programmed with the arduino software. It comes with 14 digital input/ output pins, 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; it is simply connects to a PC with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The Arduino can be powered via the USB connection or with an external power supply. The power source is selected automatically.
