Arduino Uno Hardware

This pin should be set always as output otherwise the spi interface could be put automatically into slave mode by hardware rendering the library inoperative.

Arduino uno hardware. Refer to the getting started page for installation instructions. It and version 1 0 of the arduino ide were the reference versions of arduino which have now evolved to newer releases. Arduino education is committed to empowering educators with the necessary hardware and software tools to create a more hands on innovative learning experience. Starting with what seems to be the most protruding piece of hardware on the arduino board the usb port is through where both power and data are provided to the arduino uno.

Take your students on a fun and inspiring journey through the world of programming and electronics. The environment is written in java and based on processing and other open source software. It has 14 digital input output pins 6 analog inputs a 16 mhz quartz crystal a usb connection a power jack an icsp header and a reset button. The arduino uno has 3 dedicated ground gnd pins though any pin can be coded to ground which grounds the circuit without requiring code.

For example the arduino ethernet shield uses pin 4 to control the. The atmega328 on the board comes preprogrammed with a bootloader that allows uploading new code to it without the use of an external hardware programmer. To provide power there is a 3 3 volt v pin and a 5v. Arduino uno is a microcontroller board based on the atmega328p datasheet.

The arduino uno pinout consists of 14 digital pins 6 analog inputs a power jack usb connection and icsp header. This software can be used with any arduino board. 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. The uno board is the first in a series of usb based arduino boards.

After your code is compiled using arduino ide it should be uploaded to the main microcontroller of the arduino uno using a usb connection. 11 or icsp 4. It is however possible to use any pin as the slave select ss for the devices. Arduino uno system overview before we can understand the uno s hardware we must have a general overview of the system first.

It also has a reset pin if you need to reset in the middle of your sketch. The open source arduino software ide makes it easy to write code and upload it to the board. The arduino uno has a reset button which erases the code previously loaded. Arduino genuino uno is a microcontroller board based on the atmega328p.

The arduino uno usb port type b it is a type b standard port and you will need a standard a b cable shown below to connect it to your computer.
