Arduino
The Arduino Uno R3 is an 8-bit microcontroller board featuring the ATmega328P microcontroller (MCU). This board operates at a clock speed of 16 MHz and uses a 5V logic level, making it ideal for a wide range of embedded applications. It supports the Arduino R3 Shield interconnect system and provides 14 digital I/O pins, 6 of which can be used as PWM outputs, and 6 analog input pins. It also features an ICSP header, 2KB SRAM and 1K of EEPROM. The Uno R3 is compatible with the Arduino IDE (Integrated Development Environment) for easy programming and prototyping using a C++ variant.
