Arduino Uno is a microcontroller board based on the ATmega328P and one of the most popular Arduino models. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button.

The UNO can be programmed with the EZB firmware for a variety of capabilities when connected to ARC. The tutorial to program the EZB firmware can be found HERE. This hardware was added to ARC in this beta release and newer.
