I am trying to power 4 led’s as if they are part of an RGB light strip. I am powering them off 12v, as the end goal is to add more and create my own version of a custom light strip. I am using common anode led’s and using the Arduinos PWM pins.
My question is about the use of resistors that are found in RGB strips. With all Led’s in parallel, will I need to use them? I haven’t hooked the board board up yet out of fear of blowing the LED’s, I spent $7NZD on each led, so want to check. Will the 10k resistors on the MOSFETS be enough?
The only information that I can find on these are as follows:
Specifications Size (mm) 5 Superflux 5 Superflux 5 Superflux Colour Red Green Blue Lens Waterclear Waterclear Waterclear Viewing Angle (Degrees) 60 60 60 Wavelength (nm) 643 528 468 IF Typical (mA) 20 20 20 VF Typical (V) 1.8 3.2 3.2 IV Typical (mcd) 200 900 150 IF Max Continuous (mA) 20 20 20 Preferred Value Series Resistor 5VDC 160 91 91 9VDC 360 300 300 12VDC 510 470 470
Pre-cheers and thanks for any help.
