Arduino UNO R3

Arduino is Associate in Nursing ASCII text file physical computing platform supported a straightforward i/o board and a development atmosphere that implements the Processing/Wiring language. Arduino may be accustomed develop complete interactive objects or may be connected to package on your laptop (e.g. Flash, Processing, MaxMSP). The ASCII text file IDE may be downloaded at no cost (currently for macintosh OS X, Windows, and Linux).

The Arduino Uno may be a microcontroller board supported the ATmega328. it’s fourteen digital input/output pins (of that half-dozen may be used as PWM outputs), half-dozen analog inputs, a sixteen MHz oscillator, a USB affiliation, an influence jack, Associate in Nursing ICSP header, and a button. It contains everything required to support the microcontroller; merely connect it to a laptop with a USB cable or power it with a AC-to-DC adapter or battery to urge started.

The Uno differs from all preceding boards therein it doesn’t use the FTDI USB-to-serial driver chip.

Additional options coming back with the R3 version are:
ATmega16U2 instead 8U2 as USB-to-Serial device.
1.0 pinout: another SDA and SCL pins for TWI communication placed concerning the AREF pin and 2 different new pins placed concerning the RESET pin, the IOREF that permit the shields to adapt to the voltage provided from the board and therefore the second may be a not connected pin, that’s reserved for future functions.
Stronger RESET circuit.
“Uno” means that “One” in Italian and is known as to mark the approaching unleash of Arduino one.0. The Uno and version one.0 are going to be the reference versions of Arduino, moving forward. The Uno is that the latest in a very series of USB Arduino boards, and therefore the reference model for the Arduino platform.

Features:
