Arduino UNO Pinout and Board components detail The Arduino Uno is a microcontroller board based on the ATmega328P. It has a total of 28 pins, including digital I/O pins, analog input pins, and power pins. Below is a detailed description of the pin functions It offers extensive resources and a wealth of project ideas, making it a go-to choice for educational purposes, prototyping, and a myriad of DIY electronics projects. The Arduino UNO Pins and function are described here in details. Arduino Uno is a standard board of the company, even though other boards, e.g. micro, Nano, mega, Leonardo, 101, Due and Yen. Arduino also manufactured IoT (Internet of Things), Bluetooth, GSM/3G, Wi-Fi, and motion sensor boards.
