Arduino is the go-to gear for artists, hobbyists, students, and anyone with a gadgetry dream. Arduino microcontrollers are programmed using the Arduino IDE (Integrated Development Environment). Arduino IDE Can be downloaded for free from http://arduino.cc/en/Main/Software Arduino programs, called “sketches”, are written in a programming language similar to C and C++. Many sensors and other hardware devices come with prewritten software – look on-line for sample code, libraries (of functions), and tutorials. Learn the Arduino platform and programming language to create robots, interactive art displays, electronic gadgets and much more.
