Is it possible to control the 3 legs of an RGB LED using 3 of a Core’s digital pins? If it is doable, would it be harmful to the device or LED?
(Yes, I am amateur!)
Oh, and I ask because alllll the examples I look at use Analog pins.
Oh, I think I know the answer. It is doable but since digital pins only allow High and Low, I can’t really produce too many different colors. So, it is better to Analog.
If this is correct, is there a problem to control ‘regular’ red LEDs with digital pins?
