Blinking LED with Arduino Nano

Hello friends,

Seeing a blinking LED is so much fun, but when you make one like that by yourself then the fun is even more. ^_^

So, let the fun begin,

In this tutorial, I have shown below how to blink an LED with Arduino Nano.

Note: Using an LED without a resistor will blow led.

Things you will need.

1. Arduino Nano
2. A breadboard
3. A LED ( I used 3V at 20mA led)
4. A resistor 100 ohm

Step 1: Wiring.

 

You have to attach the LED to the Nano just done in the above image.

• Connect LED's positive end to the one end of the resistor
• Another end to Nano's digital pin 13
• Negative end to Nano's ground.

To power the Nano board, you can use a USB cable or you can also connect an external power supply by connecting the positive pin to VIN and negative to the ground.

Step 2 : Coding

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
} 

 Coding for blinking LED is so simple.

• Just connect Nano to PC.

• Open Arduino IDE software.

• Go to File > Examples > Basics > Blink.

• And upload it to the Nano board.

• In no time, the LED should be Blink. 

• 1 second On, 1 second OFF.
