A usb cable is used to connect the arduino board to the pc or laptop. Each of the 14 digital pins on the arduino uno can be used as an input or output, using pinmode(), digitalwrite(), and digitalread() functions. Since it first debuted, the arduino uno has been a huge hit with electronics enthusiasts from beginner hobbyists to professional programmers. The arduino uno pinout consists of 14 digital pins, 6 analog inputs, a power jack, usb connection and. arduino reserves these for future definition and shall have no responsibility. The customer must not rely on the absence or characteristics of any features or instructions marked reserved or undefined.

Arduino uno voltage regulators how to power arduino uno: We use 14 digital pins as input or output. A complete guide on arduino uno pinout, board layout, technical specifications, important features, pin description. Arduino uno is a very valuable addition in electronics that consists of a usb interface, 14 digital i/o pins, 6 analog pins and an atmega328 microcontroller. The atmega328p microcontroller is the main chip of the arduino board. In this tutorial, we will have a brief overview about the arduino uno board, the layout of a typical uno board, some of the important specifications and finally the arduino. Last year i found some awesome arduino pinout diagrams with full colour on the arduino forums. Roland pelayo reference 1 comment 16,646 views. Thanks for the arduino uno pinout diagram, saved it in my pin. In this post i'll give you a complete and practical overview of the main arduino uno pins. The header on the left side of the board has all these analog pins together.
