I'm really new to Arduino and coding and stuff so this might be a dumb question.
I want to build some led candles, which are controlled with an Arduino board (I want to do animations with the LEDs ). I would like for all the LEDs to be individually addressable. I was thinking of using Arduino UNO, but there are only 6 PWM pins. I would like to have around 20-30 LEDs, that are individually addressable.
How can I get more PWM pins to control more LEDs? Or is there a board, that has more PWN pins?
I tried to google it, but couldn't find anything useful. If there already is a post about this, a link would be appreciated.
either a SX1509, there are even some SX1509 backpacks available, or you consider some kind of Neopixels. These are available as APA106 in a common 5mm LED form also. OK, they are RGB, but very easy to control and very easy to wire

Oh, didn’t know there were individual neopixels like that. Thanks for your help!!!
If you want to stick with ordinary PWM, you can use something like Adafruit's 16-Channel 12-bit PWM/Servo Shield.
Sparkfun carries RGB LEDs in thru hole in different sizes (3,5,8,10mm diameter), and also versions that will cycle thru colors themselves.
