Arduino® Uno Rev3

UNO The UNO is the best board for getting started with electronics and coding. If this is your first time experimenting with the platform, the UNO is the most reliable board to start with. The UNO is the most widely used and well-documented board in the entire Arduino family. Product Overview The Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (6 of which 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. It contains everything needed to use the microcontroller—simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. You can experiment with your UNO without worrying too much about making a mistake; in the worst-case scenario, you can replace the chip for a few dollars and start over. “Uno” means “one” in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0.
