The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2][3] The microcontroller 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 cir...
Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.
Arduino Uno is a microcontroller board, developed by Arduino.cc, based on the Atmega328 microcontroller and is marked as the first Arduino board developed (UNO means "one" in Italian).
In this article, we will get an overview of the basic components that make up an Arduino board. This will include talking about the brain of the Arduino i.e. the microcontroller, the pins, and the power supplies. What is an Arduino Board? Here is an overview of the whole Arduino board.
Arduino Uno is a popular microcontroller development board based on 8-bit ATmega328P microcontroller. Along with ATmega328P MCU IC, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller.
Looking at the board from the top down, this is an outline of what you will see (parts of the board you might interact with in the course of normal use are highlighted): The Arduino UNO. Starting clockwise from the top center:
The Arduino Uno pinout guide includes information you need about the different pins of the Arduino Uno microcontroller and their uses: power supply, analog and digital pins and ICSP. The guide also discusses different communication protocols used by the Arduino and a detailed diagram of the Arduino Uno board.
