Arduino
An Arduino is an open-source single-board microcontroller or small computer containing a processor core, memory, and programmable input/output peripherals. Microcontrollers are used in automatically controlled devices, such as automobile engine control systems and implantable medical devices. An Arduino microcontroller makes using electronics in projects relatively cheap and easy. The Arduino development environment or IDE is designed to introduce programming to newcomers unfamiliar with software development. It is capable of compiling and uploading programs to the board with a single click. A program written for Arduino is called a "sketch". Arduino programs are written in C++. The Arduino IDE comes with a software library, which makes many common input/output operations much easier. Users only need to define two functions to make a runnable cyclic executive program:
1) setup(): a function run once at the start of a program that can initialize settings
2) loop(): a function called repeatedly until the board powers off
Arduinos are used in SHARP devices like the cut-down circuit and in data loggers.
