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 instructable, i have shown about how to blink an LED with Arduino Nano.
Note : I didn't used resistor in this instructable before, but one of our friend told me that using led without resistor will blow led. So, i have updated instructable & added a resistor.
Things you will need.
- Arduino Nano
- A breadboard
- A LED ( I used 3V at 20mA led)
- A resistor 100 ohm
You have to attach LED to the Nano just done in above image.
connect LED's positive end to the one end of resistor and other end to Nano's digital pin 13 & negative end to Nano's ground.
to power Nano board, you can use USB cable or you can also connect a external power supply by connecting positive pin to VIN and and negative to the ground.
Step 1: The Coding Part.
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.
