The Arduino is a computer – a small computer
It can run the software you write on your PC – Arduino IDE is similar in nature to Processing IDE
You can control real-world hardware lights, motors and other computers
You can read data from real-world hardware
You can use temperature sensors, accelerometer, GPS module and many more devices with Arduino
Shields, Network, USB, GPS, LCD Screens, Touch Screen are compatible with Arduino
There is a Nano-Satellite called the ArduSat that contains a set of Arduino boards and sensors. The general public can use the Arduinos and sensors creatively while they are in space.
The processor can be easily replaced if damaged.
In 2005, building upon the work of Hernando Barragán (creator of Wiring), Massimo Banzi and David Cuartielles created Arduino, an easy-to-use programmable device for interactive art design projects, at the Interaction Design Institute Ivrea in Ivrea, Italy
