Arduino

Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board. Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs.

  • It is an open-source project, software/hardware is extremely accessible and very flexible to be customized and extended
  • It is flexible, offers a variety of digital and analog inputs, SPI and serial interface and digital and PWM outputs
  • It is easy to use, connects to computer via USB and communicates using standard serial protocol, runs in standalone mode and as interface connected to PC/Macintosh computers
  • It is inexpensive, around 30 euro per board and comes with free authoring software
  • Arduino is backed up by a growing online community, lots of source code is already available and we can share and post our examples for others to use, too!.
The Arduino development environment contains a text editor for writing code, a message area, a text console, a toolbar with buttons for common functions, and a series of menus. It connects to the Arduino hardware to upload programs and communicate with them.
There are many other microcontrollers and microcontroller platforms available for physical computing. Parallax Basic Stamp, Netmedia's BX-24, Phidgets, MIT's Handyboard, and many others offer similar functionality.
