Arduino Uno R3

The Arduino Uno R3  is a versatile and beginner-friendly microcontroller development board designed for building and prototyping a wide range of electronic projects. Powered by the ATmega328P microcontroller, it provides 14 digital input/output pins—6 of which support PWM output—and 6 analog input pins, offering flexibility to connect sensors, actuators, and other devices.

Equipped with a 16 MHz crystal oscillator, the board ensures accurate timing and stable operation. It features a USB interface for easy programming and serial communication with a computer, as well as a power jack for using external power sources. A reset button allows the board to restart the program quickly, and ICSP headers provide advanced programming options.

Fully compatible with the Arduino IDE, the Uno R3 supports a wide range of libraries, shields, and community resources, making it ideal for both beginners and experienced developers. Its compact and robust design makes it suitable for DIY electronics, robotics, educational projects, automation systems, and various prototyping applications.
