I'm new to all this and still figuring things out so don't crucify me if this is a stupid question!
I have found a small roll of these and from what I understand is that these can be color controlled from an esp32?
The question is if I only want to use like 2-3 leds to show visual feedback do I need an external power supply or can I connect them directly to the esp32 5V and run them like that?
It would be great if I can use these like that as there is probably about a 100 leds on this strip and would be much cheaper than buying individual leds on a board or using the ugly domed ones.
