It communicates using the original STK500 protocol ( reference, C header files). The ATmega328 on the Arduino Uno comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. For details, see the reference and tutorials. Select 'Arduino Uno from the Tools > Board menu (according to the microcontroller on your board). The Arduino Uno can be programmed with the ( Arduino Software (IDE)). You can find here your board warranty information. Need any help with your board please get in touch with the official Arduino User Support as explained in our Contact Us page. Need Help?Ĭheck the Arduino Forum for questions about the Arduino Language, or how to make your own Projects with Arduino. The Getting Started with Arduino Uno page contains all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.įrom the Tutorials section you can find examples from libraries and built-in sketches as well other useful information to expand your knowledge of the Arduino hardware and software.įind inspiration for your Uno projects from our tutorial platform Project Hub. If you are interested in boards with similar functionality, at Arduino you can find: 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of USB Arduino boards, and the reference model for the Arduino platform for an extensive list of current, past or outdated boards see the Arduino index of boards. 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, 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 a 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 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. Arduino Uno is a microcontroller board based on the ATmega328P ( datasheet).
