Two color led (011)

Two color LED module(011)

Introduction:

In this blog we discuss about Two color led....3mm Two color LED module KY-011 for Arduino, emits red and green light. we can adjust the amount of each color using PWM. This module is similar to KY-029.This module consist of a common cathode 3mm red/green LED and a 0Ω resistor, Since operating voltage is 2.0v ~2.5v you'll need to use limiting resistors to prevent burnout when connecting to the Arduino.

• Operating voltage - 2.0v to 2.5v
• current  -10 MA
• diameter - 5mm
• Package Type - Diffusion
  
• color - Red and Green
• Beam Angle - 150
• Wavelength - 571nm +644nm 

Things Required :

• Arduino
• Breadboard
• Jumper wire
• two color Led (011)

Code:

For on/off

int Red = 9;

 int Green = 10;

void setup() {

  pinMode(9,OUTPUT);

  pinMode(10,OUTPUT);

}

void loop() {

  digitalWrite(9,HIGH);

  digitalWrite(10,LOW);

  delay(2000);

  digitalWrite(10,HIGH);

  digitalWrite(9,LOW);

  delay(2000);

}

For pwm

int Red =9;

int Green = 10;

int val;

void setup () {

  

  pinMode (9, OUTPUT); 

  pinMode (10, OUTPUT); 

}

void loop () {

   

   for (val = 255; val> 0; val--)

      {

      analogWrite (10, val);

      analogWrite (9, 255-val);

      delay(15);

   }

   

   for (val = 0; val <255; val++)

      {

      analogWrite (10, val);

      analogWrite (9, 255-val);

      delay (15);

   }

}
