Input and Output
Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. Some pins have specialized functions:
Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the CH340G USB chip.
Classic LED Project with Nano Board
This example project shows the simplest thing you can do with an Elegoo Nano to see physical output: it blinks the onboard LED just like the star in the sky.
Hardware needed for this project:
1 x Nano Board
1 x Mini USB Cable
1 x Breadboard
2 x Wires
The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the official Arduino/Genuino UNO but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
