Details

- 3-color LED Module
- With red, green and blue output
- Great for DIY project

 

THIS MODULE DOES NOT INCLUDE CURRENT LIMITING RESISTORS. This allows the module to be used with a range of supply voltages but you must drive the LED's via an appropriate current limiting resistor otherwise damage to the LED's will occur. We will be adding an example of how to correctly drive the LED's to this page soon.

Please note that the current version of this module has a screen print error showing wrong colour order for the pinout. Please see the table below for the correct pinout.

 

Red LED Vf : 2V (approx)
Green LED Vf : 3V (approx)
Blue LED Vf : 3V (approx)

Red LED Max Ifmax : 20mA
Green LED Max Ifmax : 20mA
Blue LED Max Ifmax : 20mA

This is a simple example of how to use the RGB LED module (ARDU0021). The module has 3 separate LED's (Red, Green & Blue) which Can be individually driven by applying a voltage to the appropriate module pin. This example uses the standard Arduino analogWrite (PWM) function to cycle through the full range of colours this module is capable of producing. Please be aware that this module does NOT include current limiting resistors and therefore you should not connect this module directly to the Arduino DIO pins.
SENSOR PINOUT:
PIN 1: GREEN LED +Ve PIN 2: RED LED +Ve PIN 3: BLUE LED +Ve PIN 4: GND
