OK, this may be a dumb question, but I’m going to ask it anyway.
A few years back, I bought a bunch of RGB LEDs from SparkFun (these: https://www.sparkfun.com/products/retired/10390), that are just plain LEDs, no controller included.
I played around with them a bit when I bought them, but never really ended up using them for anything. I broke them out again today to see if they might be useful for a Halloween project, but it does not seem possible to light up more than one element (red, green, or blue) simultaneously. From that, I’m assuming that the only way to mix the colors would be to drive the individual LED pins via PWM.
The dumb question is, is that the correct assumption and/or the right way to do color mixing in this kind of RGB LED.
And yes, I do have a good supply of WS2811/2812 RGB LED strips…just don’t want to cut them up where a couple of the PIranha LEDs might do the trick.
Thanks in advance for any tips or pointers!
