Introduction: Control Built-in LED Using Push Button With Arduino Nano

About: Technology is about helping to simplify human work. I am just a enthusiast of technology and I fell in love with the Internet of Things.

Arduino has a built-in LED on digital pin 13. Now we will control it using the push button.
Let's make it!


1. Arduino Nano

2. Female to female jumper cable (3 pcs)

3. Mini USB cable

4. 220 Ohm resistor

5. Breadboard

Step 1: Wiring

Follow the wiring diagram as shown.

5 V --> one leg of push-button
Gnd --> one leg of the resistor
D2 --> the other leg of the resistor

Step 2: Code and Upload

1. Copy the code from here: Sketch
2. Paste it on the Arduino IDE
3. Connect the mini USB cable to Arduino Nano
4. Connect the USB cable to your computer
5. Click the upload button and wait for it to finish

Step 3: Do the Magic!

Push the button and see how the magic works
