The Arduino Uno is based on the Atmega328p. It is a superb board for tinkering, and has 14 digital inputs/outputs (6 are available as PWM). 6 analog inputs, 16 MHz quarts crystal, USB Connection, power jack, ICSP Header and reset button. Simply connect it to a computer with a USB Cable, or power it using a AC to DC adaptor or battery.
The Arduino Uno is most commonly used with a stepper motor shield, to run GRBL or similar firmware to control a CNC Machine. In addition to this it is a perfect board to control any type of machine or robot, and has many input/outputs to accommodate this.
