The Arduino Uno is powered by a 5V DC power supply. The power jack can be used to connect a regulated 5V power supply, or you can use the USB connection to power the Arduino Uno.

The Arduino Uno has 14 digital input/output pins (labeled D0-D13). These pins can be used to read input from sensors or to output signals to actuators. The digital pins can also be used to communicate with other devices using serial communication, SPI, or I2C.

The Arduino Uno has 6 analog input pins (labeled A0-A5). These pins can be used to read analog signals from sensors. The analog pins have a resolution of 10 bits, which means that they can read values from 0 to 1023.

The Arduino Uno also has a 16 MHz crystal oscillator. This oscillator is used to generate the clock signal for the microcontroller. The clock signal is used to synchronize the operations of the microcontroller.

The Arduino Uno has a USB connection that can be used to program the microcontroller and to communicate with the Arduino Uno using the Arduino IDE. The USB connection can also be used to power the Arduino Uno.

The Arduino Uno has an ICSP header that can be used to program the microcontroller using an external programmer. The ICSP header can also be used to connect the Arduino Uno to other devices using SPI.

The Arduino Uno is a powerful and versatile microcontroller board that can be used for a variety of projects. It is a great choice for beginners because it is easy to use and has a large community of support.
