Arduino_KY-009_3-color_full-color_LED_SMD_module_NotWorking

KY-009 37-1 3-color full-color LED SMD module

Some versions do contain additional resistors on the module. However some versions don't. In that case
 additional resistors are needed
On the internet i found examples with

  • 2 x 100 Ohm and one 180 Ohm, 
  • 3x 390 Ohm 
  • 3x 220 Ohm.

The pin layout can also be different.
My module contains the text  cnt1 / Keys / 3_Clor and -GRB is printed as pin layout and contains no additional resistors on the PCB. ( cnt1 in small letters) I also have seen variants with CNT1 in big letters and -RGB
I tried my RGB led module (after adding the additional Resistors) but i did not get my module working !

Hardware

  • Arduino pin 11 --> 100 Ohm resistor --> Pin 'B' of KY-009 module
  • Arduino pin 9   --> 180 Ohm resistor --> Pin 'R' of KY-009 module
  • Arduino pin 10 --> 100 Ohm resistor --> Pin 'G' of KY-009 module
  • Arduino GND  --> pin '-' of KY-009 module

Program

Remark : My LED module did not work!

Function

Using PWM it would be possible to get different colors on the SMD led.
