Arduino Nano is a compact and versatile board based on the ATmega328P microcontroller. It is one of the smallest Arduino boards available, but it still has all the features you need to build your project.
Arduino Nano is a great choice for projects that require a small and simple microcontroller board. Some common applications include:
To use Arduino Nano, you will need the Arduino IDE and a USB cable. Here are the steps to get started:
Here is an example of how to use the digital pins and PWM outputs on the Arduino Nano:
int ledPin = 3;
int potPin = A0;
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
int potValue = analogRead(potPin);
int ledValue = map(potValue, 0, 1023, 0, 255);
analogWrite(ledPin, ledValue);
}
This code reads the value of a potentiometer connected to analog input A0 and maps it to the range of 0-255. It then uses this value to control the brightness of an LED connected to digital pin 3 using PWM.
Arduino Nano is a powerful and versatile microcontroller board that is perfect for small and simple projects. With its compact size, it can fit into tight spaces and be used in wearable and IoT devices. With its easy-to-use IDE and simple code structure, Arduino Nano is a great choice for beginners and experts alike.
