RGB LED MODULE SMD KY-009

Description

RGB LED MODULE SMD KY-009 The KY-009 RGB Full Color LED module emits a range of colors by mixing red, green, and blue light. Each color is adjusted by using PWM. Compatible with popular electronics platforms like Arduino, Raspberry Pi and ESP32. KY-009 SPECIFICATIONS This module consists of a 5050 SMD LED and 4 male header pins. Use with limiting resistors to prevent LED burnout. Operating Voltage 5V max Red 1.8V ~2.4V Green 2.8V ~ 3.6V Blue 2.8V ~ 3.6V Forward Current 20mA ~ 30mA Operating Temperature -25°C to 85°C [-13°F ~ 185°F] Board Diemsions 18.5mm x 15mm [0.728in x 0.591in] CONNECTION DIAGRAM Connect the red pin (R) to Pin 9, the green pin (G) to pin 10, the blue pin (B) to pin 11 and finally the ground pin (-) to GND. You must use resistors between the board and the Arduino to prevent LED burnout. KY-009 Breadboard Arduino R 180Ω resistor Pin 9 G 110Ω resistor Pin 10 B 110Ω resistor Pin 11 – GND KY-009 ARDUINO CODE The following Arduino sketch will cycle through various colors by changing the PWM value on each of the three primary colors. int redpin = 11 ; //select the pin for the red LED int bluepin = 10 ; // select the pin for the blue LED int greenpin = 9 ; // select the pin for the green LED int val ; void setup ( ) { pinMode ( redpin , OUTPUT ) ; pinMode ( bluepin , OUTPUT ) ; pinMode ( greenpin , OUTPUT ) ; Serial . begin ( 9600 ) ; } void loop ( ) { for ( val = 255 ; val > 0 ; val -- ) { analogWrite ( redpin , val ) ; //set PWM value for red analogWrite ( bluepin , 255 - val ) ; //set PWM value for blue analogWrite ( greenpin , 128 - val ) ; //set PWM value for green Serial . println ( val ) ; //print current value delay ( 1 ) ; } for ( val = 0 ; val < 255 ; val ++ ) { analogWrite ( redpin , val ) ; analogWrite ( bluepin , 255 - val ) ; analogWrite ( greenpin , 128 - val ) ; Serial . println ( val ) ; delay ( 1 ) ; } }
