Hello @topquark22 , thank you for your submission. However, this only applies to some boards (particularly AVR boards). For example, the Nano RP2040 supports PWM on 20 pins (basically all pins). |

@karlsoderby What do you think about my suggestion? |

On the Uno they are screen-printed with a tilde sign. On the Nano they are not.

+On some microcontrollers PWM is only available on selected pins. Please consider the pinout diagram of your board to find out which ones you can use for PWM. They are denoted with a tilde sign (~).

@topquark22 I'm referring to the pinout diagrams that we provide. There we use the tilde symbols also for nano.

Another thing you should mention is the frequency of the PWM signal. I measured it on my scope (from a Nano) and it was 976Hz.

I guess the PWM frequency again depends on the board, so I think I wouldn't add it in this generic article. |
