Arduino Nano

Introduction

Arduino Nano inherits the advantages of Arduino development boards while featuring compact size and powerful performance. It comes in two versions: ArduinoNano328P and ArduinoNano168P. The ArduinoNano328P uses the ATmega328P microcontroller with a 16 MHz clock frequency, 32KB flash memory, and 2KB SRAM. The ArduinoNano168P uses the ATmega168P microcontroller with a 16 MHz clock frequency, 16KB flash memory, and 1KB SRAM. Arduino Nano supports various input/output interfaces including digital pins, analog pins, PWM pins, and serial communication interfaces, making it suitable for various electronic project needs.

Arduino Example Code

LED Blinking Program

int ledPin = 13;

void setup() {
  pinMode(ledPin, OUTPUT);
}

void loop() {
  digitalWrite(ledPin, HIGH);  // Turn on LED
  delay(1000);                 // Delay 1 second
  digitalWrite(ledPin, LOW);   // Turn off LED
  delay(1000);                 // Delay 1 second
}
