Blinking LED Decoration




Introduction: Blinking LED Decoration

Are you bored with your room? Does it lack style and innovation? Well how about a small decoration on the corner… is it not enough? Maybe a light blinking small decoration will do the job, better than that, how about a fully programmable one where you can control the color succession and the rhythm… This instructable will show you how I turned an ordinary decoration item into a decorative flashing lights

Step 1: Get Your Things.

To build this project you need:

  • An Arduino UNO or compatible.
  • Your decoration item.
  • LEDs: Different colors of your choice.
  • Some male to male jumper wires (10 pieces are enough).
  • A mini breadboard.

Step 2: Get Things in Order:

first of all,connect all your LEDs on the mini breadboard, here I chose two leds by colors to have enough luminosity for better results. Next after doing all the wiring put the mini breadboard inside your item.

Step 3: Programming the Arduino UNO

Past the following code into the Arduino software and upload it to the device; in this code I used 5 colors you could change it by changing the number of LEDs

int led = 2;

int led2 = 3;

int led3 = 4;

int led4 = 5;

int led5 = 6;

// the setup routine runs once when you press reset:

void setup() {

// initialize the digital pin as an output.

pinMode(led, OUTPUT);

pinMode(led2, OUTPUT);

pinMode(led3, OUTPUT);

pinMode(led4, OUTPUT);

pinMode(led5, OUTPUT);


// the loop routine runs over and over again forever:

void loop() {

digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)

delay(1000); // wait for a second

digitalWrite(led, LOW); // turn the LED off by making the voltage LOW

digitalWrite(led2, HIGH);


digitalWrite(led2, LOW);

digitalWrite(led3, HIGH);


digitalWrite(led3, LOW);

digitalWrite(led4, HIGH);


digitalWrite(led4, LOW);

digitalWrite(led5, HIGH);


digitalWrite(led5, LOW);

// wait for a second


Step 4: Enjoy :)!!
