Description
This is the SMD RGB LED Common Cathode Module, This 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 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.
Module Connections
There is a 4-pin header on the assembly for making connections.
1 x 4 Header
- GND / – = Ground
- G = Green LED anode. Connects to digital output/PWM pin on uC. Active HIGH
- R = Red LED anode. Connects to digital output/PWM pin on uC. Active HIGH
- B = Blue LED anode. Connects to digital output/PWM pin on uC. Active HIGH
NOTE: On some modules, we have found the labeling on the R and G channels to be swapped. If you go by our connection diagram, you should be good to go.
