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.

There are six ICSP pins available on the Arduino board that can be hooked to a programmer device via a programming cable. Know your Pinout. The Arduino Uno Microcontroller is one of the most versatile boards on the market today and that’s why we decided to focus on it in this guide.

The Arduino Uno pins compatible with PWM are the pins 3, 5, 6, 9, 10 and 11. So you have 6 pins where you can create a PWM, using the analogWrite() function. This can be quite useful to control some actuators that require a fine voltage tuning, and are not only switched on or off.

Arduino UNO Pinout – Analog Pins. The Arduino UNO has 6 analog input pins labeled from A0 to A5 as shown in the figure below. Those pins can be used with analog peripherals in the Arduino microcontroller such as: ADC (A/D Converter) and the Analog Comparator.

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 · There are a couple of ways in which you can power the UNO board. The first and easy way is using the Type-B USB Connector. The next way is to provide an unregulated supply in the range of 6V to 20V to VIN pin of the UNO (Pin number 26).

Feb 11, 2025 · Arduino UNO Pinout. Arduino UNO R3 pin diagram shows that it has 6 analog inputs, 14 digital input/output pins (of which 6 can be used as PWM outputs), a 16 MHz ceramic crystal resonator, a USB-B port, an ICSP header, Atmega328p and Atmega 16U2 processor, a power jack and, a reset button.

6 x Analog input pins. They can also be used as digital input/output pins. ※ NOTE THAT: For the pins are named with the prefix of 'D' (e.g. pin D1, D2 ...), It call be called without prefix of 'D', (e.g. pin 1, 2 ...) Each pin can be used with diferent functionalities. However, at a time, each pin can be used only with one functionalitity.

Jun 1, 2020 · You need to simply connect it to a computer with a USB cable for programming and power it with a AC-to-DC adapter or battery to get started to run. The Arduino Uno does not use the FTDI USB-to-serial driver chip. it features the Atmega8U2 microcontroller chip programmed as a USB-to-serial converter.

Connect the board to your computer using a USB cable for power and programming. Alternatively, use an external power supply (7-12V) connected to the VIN pin or the power jack. Use digital pins (D0-D13) for digital input/output operations. For PWM …
