Hello, I am using the Arduino Nano fo controlling some LEDs through an NPN transistor. My question is how can I get above 20kHz so the PWM cant be heard. Also, I read that it will decrease the resolution of it ( those are the steps from 0-255 right?)well I need only 99 steps. Also, my transistors are connected to pins 9 and 10 of the Arduino nano. Last question I heard that there is also some sort of library that can do this?
Thanks in advance.If you need any more info just tell me. And also have a nice day
