The Arduino is a type of open source hardware. Using an Arduino is fairly straightforward: buy a board and attach it to a personal computer via a cable.
Then load instructions into the Arduino's processor via the personal computer, William Gurstelle explained.
Once programmed, the Arduino makes decisions based on the information transmitted by whatever sensors you've hooked up, and does something corporeal, such as turn on or off the motors, displays, valves, and lights attached to it.
Arduino, a small, open-source hardware microcontroller platform has been turning heads in it’s flexibility as a prototyping platform for a dizzying array of applications, from oscillators to robots to 3d printers, just to name a few.
This documentary interviews the revolutionary beginning of the creators behind this movement, and touches upon what it will mean for students, engineers, and garage tinkerers alike.
