SMD RGB LED Module
RGB LED module LED is made from a patch full color, by R, G, B three-pin PWM input voltage can be adjusted in three primary colors (red / blue / green) strength in order to achieve full color mixing effect. Control module with Arduino cool lighting effects can be achieved.
This is the SMD RGB LED Common Cathode Module, These module has 3 separate LEDs the Red, Green and Blue which can be individually driven by applying a voltage to the appropriate module pin this example code is uses the Arduino analogWrite(PWM) function to cycle through the full possible output colors this smd led module is capable of producing a rainbow color scheme.
NOTE: This module does not include current limiting resistor and therefore you should not connect this module directly to the Arduino DIO pins. This allows the module to be used with a range of supply voltages but you must drive the LED via an appropriate current limiting resistor otherwise it will be unusable.
