Descrição

SMD RGB LED module consists of a full-color LED made by R, G, B three pin PWM voltage input can be adjusted. Primary colors (red / blue / green) strength in order to achieve full color mixing effect. Control of the module with the Arduino can be achieved Cool lighting effects.Specificationsusing 5050 full color LED with max current of 20mAForward Voltage : Red 1.80V (2.4 max), Green,Blue 2.8V (3.6V)RGB trichromatic limiting resistor to prevent burnoutthrough the PWM adjusting three primary colors can be mixed to obtain different colorswith a variety of single-chip interfaceOperating voltage: 5VLED drive mode: common cathode driverSchemaSince you can’t connect the led’s directly to the Arduino you will need resistors!!Arduino pin 9 –> 180 Ohm resistor –> Pin ‘R’ of KY-009 moduleArduino pin 10 –> 100 Ohm resistor –> Pin ‘G’ of KY-009 moduleArduino pin 11 –> 100 Ohm resistor –> Pin ‘B’ of KY-009 moduleArduino GND –> pin ‘-‘ of KY-009 module—————————————————————–Example Code—————————————————————-int redpin = 11; // select the pin for the red LEDint bluepin = 10; // select the pin for the blue LEDint greenpin = 9; // select the pin for the green LEDint val=0;void setup () { pinMode (redpin, OUTPUT); pinMode (bluepin, OUTPUT); pinMode (greenpin, OUTPUT); Serial.begin (9600);} void loop () { for (val=255; val>0; val–) { analogWrite (11, val); analogWrite (10, 255-val); analogWrite (9, 128-val); delay (1); } for (val = 0; val <255; val++) { analogWrite (11, val); analogWrite (10, 255-val); analogWrite (9, 128-val); delay (1); } Serial.println (val, DEC);}
