Description: 1. Microcontroller: Arduino Uno R3 is a microcontroller board based on the ATmega328P chip, which can be programmed using the Arduino Integrated Development Environment (IDE). 2. Input-Output Pins: It features 14 digital input-output pins (6 of them can be used as PWM outputs), 6 analog inputs, an ICSP header, and a USB connection for programming and communication. 3. USB Connection: Arduino Uno R3 comes with a USB connection, which not only enables programming but also acts as an interface to power the board via a computer or an external power supply. 4. Power Supply: The board operates on 7-12V DC (unregulated) or 7-12V DC (regulated) depending on the use of the voltage regulator module. An Automatic Reset function is available in case the input voltage falls below a certain level during operation. 5. Memory: Arduino Uno R3 comes with 32 KB Flash memory and 2 KB SRAM for storing program data, as well as 1 KB EEPROM for non-volatile user memory. 6. Programming Language: It can b
