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
