Description: 1. Microcontroller: Arduino UNO R3 is a microcontroller board based on the ATmega328P chip with SMD (Surface Mount Device) version of the ATmega328. It's an upgrade from the standard through-hole ATmega328 in previous UNO versions, providing smaller size and improved heat dissipation. 2. Compatibility: This Arduino board is compatible with most Arduino shields, ensuring expanded functionality and versatility for various projects. The SMD ATmega328 does not cover the ISP pins, but you can still use ICSP header or an external USB-ASP programmer for chip programming. 3. Digital and Analog I/O: UNO R3 offers 14 digital input/output pins (6 PWM), 6 analog inputs, a 10-bit ADC resolution, and 6 analog output pins. This range is perfect for creating projects involving sensor interfacing or LED control. 4. USB Interface: The board includes a USB connection that allows the user to upload code directly from their computer using the Arduino IDE without needing any external programmers. Additi
