Arduino Uno R3

What is Arduino Uno R3?

The Arduino Uno R3 is open-source integration (microcontroller) that reflects the Atmega328 chip module. This mechanism further unites 14 digital (input/output) pins, a B-type USB port for connection, 6 analog input pins, an Onboard ceramic resonator (16 MHz), an ICSP header, a DC power jack, as well as a microcontroller reset button.

You need an Integrated Development Environment (IDE) to write programs on the board. The in-circuit system programming or ICSP header can be helpful for alternative programming interfaces. The Arduino boards have a massive support community that you can access through arduino.cc/forum.
