Does the square-wave nature of PWM dictate how much resistance you need?
Say I want to power 10 LEDs with PWM with my Mega 2560. I have a bunch of 200 ohm resistors. … That's if PWM was true analog.
However, PWM is not true analog, and if I analogWrite 4V to each pin, they're going to spend most of the time at 5V and some of the time at 0V. …
