Arduino Uno R3 is an ATmega328P microcontroller-based development board.

This is widely popular in Embedded electronics because of the available resources and easy to use by everybody features. With 14 digital input/output pins where 6 can be configured and used as PWM outputs, 6 as analog inputs is a great addition for I/O related operations. Powered with a 16 MHz ceramic resonator, an USB connection, a power jack, an ICSP header, and a reset button.

It includes a LED that can be useful in multiple applications or to test the board functionality. A voltage regulator, better to say an LDO, is available inside this development board to make this Arduino compatible for a wide range of input voltages. The application is very easy, just upload the code, and run.
