KY-011 Two Color LED module
Short description :
The KY-011 Two Color LED module emits red and green light. You can adjust the intensity of each color using PWM.
Working with (Compatible)
Arduino, ESP32, Nodemcu, ESP8266, Raspberry Pi, and ......
ARDUINO IDE CODE
Example description :
Arduino sketch will gradually alternate between red and green colors.
int redpin = 11; // pin for red signal
int greenpin = 10; // pin for green signal
int val;
void setup() {
pinMode(redpin, OUTPUT);
pinMode(greenpin, OUTPUT);
}
void loop() {
for(val = 255; val > 0; val--) {
analogWrite(redpin, val); //dim red
analogWrite(greenpin, 255 - val); // brighten green
delay(15);
}
for(val = 0; val < 255; val++) {
analogWrite(redpin, val); //brighten red
analogWrite(greenpin, 255 - val); //dim green
delay(15);
}
}
