Characteristics of Arduino Uno R3 microcontroller

The Arduino Uno R3 with Cable is a microcontroller board based on

Arduino Uno Micro Controller The Arduino Uno is a micro controller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs). 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the micro controller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
