Night Light

Hi,

This code is that this LED changes automatically. Otherwise, we would have to change the wires so that it remains fixed to a color, but this code changes it automatically.

Explanation:

With this code, it sends power to the breadboard and to the desired LED pin.

Code:

// RGB LED

// The RGB LED will appear red, green, and blue first, then red, orange, yellow, green, blue, indigo, and purple.

const int greenPin = 10; // G petal on RGB LED module connected to digital pin 10

const int bluePin = 9; // B petal on RGB LED module connected to digital pin 9

/**************************************************************************/

{

pinMode(redPin, OUTPUT); // sets the redPin to be an output

pinMode(greenPin, OUTPUT); // sets the greenPin to be an output

pinMode(bluePin, OUTPUT); // sets the bluePin to be an output

}

// Basic colors:

color(255, 0, 0); // turn the RGB LED red

delay(1000); // delay for 1 second

color(0, 255, 0); // turn the RGB LED green

delay(1000); // delay for 1 second

color(0, 0, 255); // turn the RGB LED blue

delay(1000); // delay for 1 second

// Example blended colors:

color(255, 0, 252); // turn the RGB LED red

delay(1000); // delay for 1 second

color(237, 109, 0); // turn the RGB LED orange

delay(1000); // delay for 1 second

color(255, 215, 0); // turn the RGB LED yellow

delay(1000); // delay for 1 second

color(34, 139, 34); // turn the RGB LED green

delay(1000); // delay for 1 second

color(0, 112, 255); // turn the RGB LED blue

delay(1000); // delay for 1 second

color(0, 46, 90); // turn the RGB LED indigo

delay(1000); // delay for 1 second

color(128, 0, 128); // turn the RGB LED purple

delay(1000); // delay for 1 second
