Arduino is an open-source platform for building electronics projects:
A programmable device that allows users to interact with external hardware devices using software programs
Arduino boards can read inputs, like light on a sensor or a finger on a button, and turn them into outputs, like activating a motor or turning on an LED .
Arduino is used in many different projects, such as robotics, security, music, and other STEM fields
Users can tell their board what to do by sending a set of instructions to the microcontroller on the board using the Arduino programming language and the Arduino Software (IDE)
