It's annoying to have to guess what 0-255 LED color value corresponds to the color you want in your project. This eliminates the guesswork.

Hello, I like TTL. It can handle TTL well, but it is difficult to deal with firmware. I would like to study this and hear the advice of several engineers.

  Are you sure? yes | no
