Arduino Uno rev 3 development board

This is the reference Arduino version of the prototype, because many tutorials use this version of Arduino as a reference board.

Arduino Uno Rev 3 is a microcontroller board.

This is the reference Arduino version of the prototype, because many tutorials use this version of Arduino as a reference board.

It has the same dimensions as Arduino 101, Arduino Zero, Arduino Yún, Arduino Leonardo, Arduino Uno Wifi rev 2 and Arduino Ethernet.

It comes with an 8-bitMicrocontroller, OneATmega328P, It comes with 32 KB of flash memory, 2 KB of SRAM and 1 KB of EEPROM.

The Arduino runs at a frequency of 16MHz under a voltage of 5V and can be powered through the recommended input range of 7V to 12V.

In terms of I/O, the Arduino Uno has a USB-B port, which the computer can use to transfer new programs to run, power input and a set of I/O pins. It has 20 I/O pins, 14 digital pins and 6 analog pins with 10-bits, with mapping values from 0 to 1023.

In the above picture, we can see 14 digital I/O pins on the top, which can be configured as output pins or input pins by programming.

At the bottom, we have power pins and 6 analog input pins.

There is a built-in LED pin connected to pin 13, which can provide us with status information.

The Arduino Uno has a USB port that allows you to connect it to a computer and load programs on the computer.

Arduino has no operating system and runs one program at a time.

After the program is loaded, you can start the program as long as you supply power to the Arduino through the USB or through the AC to DC power cord or battery through the power port. This means that once the program is loaded, the Arduino can be placed on a mountain with solar panels and batteries, and it will run until there is power.
