Description

The Arduino Uno Rev3 is designed around the ATmega328P microcontroller. It provides digital and analog input/output pins that allow it to interact with components such as LEDs, buttons, sensors, motors, displays, and relays.

Programs, commonly called sketches, can be written using the Arduino programming environment and uploaded to the board through USB. Its simple design and large ecosystem of libraries, shields, tutorials, and compatible components make the Uno Rev3 particularly suitable for beginners, students, hobbyists, and rapid prototyping.
