Welcome to RoboThings! If you're new to Arduino Nano and eager to dive into the world of microcontrollers, you've come to the right place. In this guide, we'll walk you through setting up your Arduino Nano using the Arduino IDE, and we'll even show you how to use libraries to enhance your projects. Let's get started!
What You’ll Need
Before we begin, make sure you have the following:
- Arduino Nano board
- USB cable (A to Mini-B or A to Micro-B, depending on your Nano version)
- Computer with Arduino IDE installed
- Basic electronic components (LED, resistor, breadboard, and jumper wires)
Step 1: Install the Arduino IDE
If you haven’t already, download and install the Arduino IDE from the official Arduino website.
Step 2: Connect Your Arduino Nano
Connect your Arduino Nano to your computer using the USB cable. Once connected, your computer should recognize the device. If it’s the first time you’re connecting the Nano, it may take a moment for the drivers to install automatically.
Step 3: Configure the Arduino IDE
Open the Arduino IDE. You’ll need to configure it to communicate with your Arduino Nano. Here’s how:
Select the Board:
- Go to
Tools > Board > Arduino Nano
.
- Go to
Select the Processor:
- Depending on your Nano version, select the correct processor. For older Nanos, choose
ATmega328P (Old Bootloader)
. For newer ones, selectATmega328P
.
- Depending on your Nano version, select the correct processor. For older Nanos, choose
Select the Port:
- Go to
Tools > Port
and select the COM port to which your Nano is connected. It usually looks something likeCOM3
orCOM4
on Windows and/dev/ttyUSB0
or/dev/ttyACM0
on Linux.
- Go to
Step 4: Upload a Test Sketch
Now, let’s upload a simple sketch to test your setup. We’ll use the Blink example, which makes the onboard LED blink.
Open the Blink Sketch:
- Go to
File > Examples > 01.Basics > Blink
.
- Go to
Upload the Sketch:
- Click the upload button (right arrow) in the Arduino IDE. The IDE will compile the code and upload it to your Arduino Nano.
If everything is set up correctly, the onboard LED on your Arduino Nano should start blinking!
Step 5: Using Libraries
Libraries are an excellent way to extend the functionality of your Arduino projects. Let’s install and use a library to control an external LED.
Install a Library:
- Go to
Sketch > Include Library > Manage Libraries
. - In the Library Manager, search for
FastLED
and install it. FastLED is a popular library for controlling LED strips and individual LEDs.
- Go to
Use the Library in Your Sketch:
- Create a new sketch and include the FastLED library at the beginning of your code:
#include
#define LED_PIN 6
#define NUM_LEDS 1
CRGB leds[NUM_LEDS];
void setup() {
FastLED.addLeds(leds, NUM_LEDS);
}
void loop() {
leds[0] = CRGB::Red;
FastLED.show();
delay(500);
leds[0] = CRGB::Black;
FastLED.show();
delay(500);
}

- Connect an External LED:
- Connect an LED to pin 6 on your Arduino Nano, with a resistor in series to limit current. The other end of the LED goes to the ground.
- Upload the Sketch:
- Upload the sketch to your Arduino Nano. The external LED should start blinking red.
