The arduino uno is a microcontroller board based on the atmega328 . and quot; uno and quot; means one in Italian and is named to mark the upcoming release of arduino 1.0. It has 14 digital input or output pins , 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 microcontroller, simply connect it to a computer with a usb cable or power it with a ac-to-dc adapter or battery to get started. The uno differs from all preceding boards in that it does not use the ftdi usb-to-serial driver chip. Instead, it features the atmega16u2atmega8u2 up to version r2) programmed as a usb-to-serial converter. This is your first step towards interfacing the lcd and keypad with your arduino.
