اردينو uno ، يکي از محبوب ترين برد هاي اردينو که بر پايه ميکروکنترلر atmega 328 بنا شده است. اين برد 14 پين ورودي و خروجي ديجيتال و 6 پين ورودي انالوگ ( که ميتوان به عنوان خروجي PWM استفاده نمود) را دارا ميباشد.وجود چيپ usb to serial روي برد باعث شده اين برد از هرگونه پروگرمر و مبدل بي نياز باشد.اين برد قابليت راه اندازي طيف وسيعي از چيپست ها و ماژول هاي موجود در بازار را دارد.شما با استفاده از اين برد به سادگي ميتوانيد وارد دنياي الکترونيک شويد و محصولات و حتي کار دستي هايتان را هوشمند کنيد.

The Arduino UNO is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc . The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. The board has 14 Digital pins, 6 Analog pins (can be used as PWM outputs), and programmable with the Arduino IDE (Integrated Development Environment) via a type B USB cable.[4] It can be powered by the USB cable or by an external 9-volt battery, though it accepts voltages between 7 and 20 volts. It is also similar to the Arduino Nano and Leonardo.The hardware reference design is distributed under a Creative Commons Attribution Share-Alike 2.5 license and is available on the Arduino website. Layout and production files for some versions of the hardware are also available.
