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?
Thanks!
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.
