RGB Lights Compaing Three LED Lights Red,Green & Blue. We Adjusting the Brightness Of the LED it Create new Colour. So the LED Adjusting Brightness using Codes(0-255).

►As the LEDs are very close to each other, we can only see the final colors result rather than the three colors individually. ►To have an idea on how to combine the colors, take a look at the following chart. This is the simplest color mixing chart, there are more complex color charts on the web. ►RGB LEDs have 4 pins which can be distinguished by their length. The longest one is the ground (-) or voltage (+) depending if it is a common cathode or common anode LED, respectively.

RGB LED is acombination of 3 LEDs in just one package
· 1x Red LED

· 1x Green LED

· 1x Blue LED

The color produced bythe RGB LED is a combination of the colors of each one of these three LEDs.

Step 1: Mixing Colors

To produce other colors, you can combine the three colors in different intensities. To generate different colors you can use PWM to adjust the brightness of each LED. As the LEDs are very close to each other, we can only see the final colors result rather than the three colors individually.

R G B (255,255,255)= White color The 255 is full brightness of the led light

Step 2: RGB LED Two Types:

Step 3: RGB LED BLINK:

int redPin = 11;
int greenPin = 10; int bluePin = 9; void setup() { pinMode(redPin, OUTPUT); pinMode(greenPin, OUTPUT); pinMode(bluePin, OUTPUT); } void loop() { setColor(255, 0, 0); // red delay(1000); setColor(0, 255, 0); // green delay(1000); setColor(0, 0, 255); // blue delay(1000); setColor(255, 255, 0); // yellow delay(1000); setColor(80, 0, 80); // purple delay(1000); setColor(0, 255, 255); // aqua delay(1000); } void setColor(int red, int green, int blue) { #ifdef COMMON_ANODE red = 255 - red; green = 255 - green; blue = 255 - blue; #endif analogWrite(redPin, red); analogWrite(greenPin, green); analogWrite(bluePin, blue); }

Step 4: ARDUINO UNO USING BLUETOOTH RGB CONTROLLER:

int color =0;
int red = 12; int green =11; int blue =10;

char received;

void setup() { Serial.begin(9600); pinMode(red, OUTPUT); pinMode(green, OUTPUT); pinMode(blue, OUTPUT);

analogWrite(red,0); analogWrite(green,0); analogWrite(blue,0); }

void loop(){ if(Serial.available()>0){ color = Serial.read(); char Rec = char(color); if (Rec != '0') { Serial.println(Rec); } } //Black if (color == 'B') { analogWrite(red,0); analogWrite(green,0); analogWrite(blue,0); }

//WHITE if (color == 'W') { analogWrite(red,255); analogWrite(green,255); analogWrite(blue,255); }

//RED if (color == 'R') { analogWrite(red,255); analogWrite(green,0); analogWrite(blue,0); }

//LIME if (color == 'L') { analogWrite(red,0); analogWrite(green,255); analogWrite(blue,0); }

//BlUE if (color == 'E') { analogWrite(red,0); analogWrite(green,0); analogWrite(blue,255); }

//Yellow if (color == 'Y') { analogWrite(red,255); analogWrite(green,255); analogWrite(blue,0); }

//Cyan/Aqua if (color == 'C') { analogWrite(red,0); analogWrite(green,255); analogWrite(blue,255); }

//Magenta / Fuchsia if (color == 'M') { analogWrite(red,255); analogWrite(green,0); analogWrite(blue,255); }

// Maroon if (color == 'F') { analogWrite(red,128); analogWrite(green,0); analogWrite(blue,0); }

// Olive if (color == 'O') { analogWrite(red,128); analogWrite(green,128); analogWrite(blue,0); }

//Green if (color == 'G') { analogWrite(red,0); analogWrite(green,128); analogWrite(blue,0); }

// Purple if (color == 'P') { analogWrite(red,128); analogWrite(green,0); analogWrite(blue,128); }

// Navy if (color == 'N') { analogWrite(red,0); analogWrite(green,0); analogWrite(blue,128); }

//light coral if (color == 'J') { analogWrite(red,240); analogWrite(green,128); analogWrite(blue,128); }

//orange red if (color == 'X') { analogWrite(red,255); analogWrite(green,69); analogWrite(blue,0); }

//green yellow if (color == 'G') { analogWrite(red,173); analogWrite(green,255); analogWrite(blue,47); }

// spring green if (color == 'S') { analogWrite(red,0); analogWrite(green,255); analogWrite(blue,127); }

// aqua marine if (color == 'A') { analogWrite(red,127); analogWrite(green,255); analogWrite(blue,212); }

// hot pink if (color == 'H') { analogWrite(red,255); analogWrite(green,105); analogWrite(blue,180); }

// honeydew if (color == 'D') { analogWrite(red,240); analogWrite(green,255); analogWrite(blue,240); }

// light gray / light grey if (color == 'U') { analogWrite(red,211); analogWrite(green,211); analogWrite(blue,211); } }
