The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform for an extensive list of current, past or outdated boards see the Arduino index of boards.
Arduino uno software#
The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. "Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. You can tinker with your Uno without worrying too much about doing something wrong, and in the worst case scenario you can replace the chip for a few dollars and start over again. It contains everything needed to support 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.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. The Arduino Uno is a microcontroller board based on the ATmega328P ( datasheet).
The UNO is the most used and documented board of the whole Arduino family. If this is your first experience tinkering with the platform, the UNO is the most robust board you can start playing with. The Arduino UNO is one of the best boards to get started with electronics and coding.
