This board introduces you to the unique Arduino experience, making it perfect for learning the basics of sensors and actuators. It’s also an essential tool for rapid prototyping. The Arduino Uno is the most widely used and documented board in the world. The name “Uno”, which means “one” in Italian, was chosen to mark the release of Arduino Software (IDE) 1.0, which has since evolved into newer versions. The board has 14 digital input/output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal, a USB connector, a power jack, an ICSP header, and a reset button. Arduino is an open source hardware, software, and content platform with a global community of over 30 million active users.
