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

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.

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.

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);

delay(1000);

digitalWrite(led2, LOW);

digitalWrite(led3, HIGH);

delay(1000);

digitalWrite(led3, LOW);

digitalWrite(led4, HIGH);

delay(1000);

digitalWrite(led4, LOW);

digitalWrite(led5, HIGH);

delay(1000);

digitalWrite(led5, LOW);

// wait for a second
