4. What is Arduino
Arduino® is an open-source prototyping platform based in easy-to-use hardware and software. Arduino® boards
are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an
output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to
do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino
programming language (based on Wiring) and the Arduino® software IDE (based on Processing).
