Jan 9, 2025 · Arduino Uno has 14 digital input/output pins (out of which 6 can be used as PWM outputs), 6 analog input pins, a USB connection, A Power barrel jack, an ICSP header and a reset button. Arduino UNO Pin Layout Overview

Sep 10, 2024 · 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 UNO Pinout along with the pin description.

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.

Feb 11, 2025 · Complete Arduino Uno pinout configuration with detailed pin explanations such as PWM, SIP, I2C. Your every question will be answered in this..

Here’s a global visual description of all the pins you can find on an Arduino Uno board. You may find that quite difficult to understand at first. So, let’s break down each kind of pin, one by one.

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.

Here is a detailed Arduino UNO Pinout Diagram with colored labels and legends to help you easily identify the functionalities that each pin can perform. It also has the Atmega328p AVR microcontroller pinout diagram to ease the mapping from the Arduino IO numbered pins to the actual microcontroller’s pins.

Aug 18, 2019 · The 14 digital input/output pins can be used as input or output pins by using the pinMode(), digitalRead() and digitalWrite() functions in the Arduino IDE. Each pin operates at 5V and can provide or receive a maximum of 40mA current, and each pin also has an internal pull-up resistor of 20-50 KOhms which are disconnected by default.

In addition to the specific functions listed below, the digital pins on an Arduino board can be used for general purpose input and output via the pinMode (), digitalRead (), and digitalWrite () commands.
