Hi,
As a newbie, I have no clue how to calculate the resistors for this vma318 led kit. On the specs their is no forward voltage. Unfortunately I only know how to calculate the resistors when the forward voltage is known. Can someone help me? I’m planning to use this with an arduino 5v.
Thank you in advance,
Maurice
Is there no one who can help me?
Unfortunately the forward is not given on the web page.
However there is guide you can download that can help

and I think this is the data sheet for the SMD 5050 RGB LED.

I hope this helps.
Thank you for the info. I had found several SMD5050 sheets, but not this one.
I think I can make it work with this.
No problem,
I hope everything works out well for you.
