Positive terminal RGB LEDs
December 29, 2010
Recently I got few 10mm RGB LEDs. The strange thing is: the longer pin is positive? This is what is says on eBay:
10mm Ultra-Bright RGB LED 7000-9000 mcd
Emitted Colour : Red / Green / Blue
Pins sequence: RED/Common Anode(positive terminal)/Green/Blue
Lens Color : Water Clear
Forward Voltage (V) : 2.5~3.2
View Angle: About 40 degree.
Luminous Intensity: 7000/8000/9000mcd
My question is, what is the proper way to have all three color working to connect to arduino or other controller? So far I only know they usually have longer ping in Ground negative, but for this one, I never seen.
Thanks for anyone who could help!!
