LED 1 Dimmer LED 2 Dimmer LED 3 Dimmer for example LED 1 = 11 pin brightness turn on, LED 2 = 12 pin brightness turn on, I want to control them all separately. Now I can control only one of them. My knowledge is not working for me. Can someone share C # sample code with ardunio codes? Please help me.

Robin’s updated Serial Input Basics can give you ideas (assuming you are using serial communication although the principles can also be applied to other ways of communication).
