RGB led question!

Hi, I want to use an RGB LED, but I'm not going to do anything with the brightness. I'm going to keep the brightness fixed. Do I still need to use PWM pins on the Arduino?


No, you don't need PWM. The 3 internal LEDs can simply be turned on & off.

Hi, Do remember you need resistors for each color pin; probably 150 .. 470 ohms is good.

And a different value to for each color, get the same appearent brightness. the threshold currents are different as is your color perception.
